Ask HN: How much coffee do you drink as a programmer?

• alienspaces 6y ago
  Two first thing in the very early morning, one after the other. Maybe one in the afternoon... Or a nap
• ferros 6y ago
  Don’t forget for smokers that your body metabolises caffeine around twice as fast
• camjohnson26 6y ago
  Easily 2 pots for me, probably average 6-7 cups.

  Zero. Probably an outlier. It doesn't do me anything.
  • conductr 6y ago
    I’m in this club. I enjoy the taste but just don’t get the mass appeal/obsession. Also, always living in a generally hot climate (Texas) has me usually avoiding hot drinks. I know there are cold products now, but I’m too old to start a new habit.
  • aeurielesn 6y ago
    Zero as well. I drink tea without caffeine.
  • glandium 6y ago
    Zero here too. I hate the taste. I hate the smell. And I'm French, so usually people have a sort of look of disbelief when I say that.
    • DougN7 6y ago
      You are not alone. Smells/tastes like burnt dirt to me.
    • tothrowaway 6y ago
      I hate the smell too. I commented to a friend that coffee smells like canned tuna. She thought I was making it up, and Googled it. Turns out, I'm not the only one: http://thefrenchexit.blogspot.com/2012/02/why-does-coffee-smell-fishy.html http://thefrenchexit.blogspot.com/2012/02/why-does-coffee-sm...
  • mlvljr 6y ago
    Lads, I'm in the club too. Don't like the taste either.
• simonblack 6y ago
  Used to drink 6-10 cups a day, even one at bedtime. These days, it's one or two in the morning for breakfast. I find I work better if I am more relaxed than if I'm wide awake. All-niters are a thing that is gone decades ago.
• quixquaxqux 6y ago
  Since quarantine and WFH I'm pretty sure I've been overdosing. Earlier this week I was feeling anxious, jittery, and dehydrated. Detoxed from caffeine Wed-Fri and today (Sat) feeling much better. Will ease back into 1 cup a day and drink more water.
• keiferski 6y ago
  A piece of advice: Every day, once a day, give yourself a present. Don't plan it. Don't wait for it. Just let it happen. It could be a new shirt at the men's store, a catnap in your office chair, or two cups of good, hot black coffee.
  • docdeek 6y ago

• jcuenin 6y ago
  I don't drink coffee, just water or tea sometimes :)
• non-entity 6y ago
  Not a lot. I'm not a huge coffee fan, I'll drink it if it's free and theres nothing else and occasionally I'll buy one, however.
• coder4life 6y ago
  About 3/4 of a large pot, so about 3 large coffees
• darkr 6y ago
  Between 2 and 8 cups per day. Usually switch to tea or water later in the afternoon.
• mysticmode 6y ago
  I drink around 7 to 8 times a day. People say it's bad, but who cares.. I'm just enjoying my coffee and a good smoke everyday.
• bdibs 6y ago
  I work from home, use an Aeropress, and drink between 4-6 cups of black coffee per day. Once it starts getting late I’ll sometimes throw in a cup of green tea.
• milansm 6y ago
  I quit coffee as part of New Year's resolution. I started feeling nauseous in the morning if I drank a cup of coffee in the afternoon the day before. Once I quit, I thought I'll be less productive, and that I won't be able to focus, but after a week or two, my body recovered from the caffeine addiction. I started drinking black tea - two cups per day. It's still caffeine, but in far less amount. I miss coffee, though. I miss its smell and taste and somehow I correlate coffee with work satisfaction, creativity, and being productive. It's probably because the coffee is marketed around work culture, and I bought that.
  • dmarchand90 6y ago
    Also quit coffee to switch exclusively to green tea. I was just getting too much anxiety. I definitely feel much calmer without coffee. In general for I think I was a great move, I work a little less, but when I work it tends to be on more relevant things. I'll typically have one cup of coffee one day on the weekend, especially if I'm going to do something to burn the energy (hiking/biking). EDIT: technically not a programmer but a grad student in a computational field, but I think it's very similar work mentally
• csa 6y ago
  Not currently working as a programmer, but I have worked as one in the past. I only drink decaf, and I will have a cup a few times a week that I make as a pour over for myself. If I am feeling crazy, I will make two. I am very sensitive to caffeine, and it impacts my sleep very negatively. I tried decreasing caffeinated coffee to half a cup early in the day (e.g., 8 or 9 am), and it didn't matter. I sleep much better when I don't drink caffeinated coffee (or any drink that has very much caffeine). That said, my understanding is that decaf actually has a small amount of caffeine, but it does not seem to impact my sleep at all. I wonder if the amount of caffeine is actually that low in decaf.
• eldelshell 6y ago
  2 capuccinos/lattes: breakfast & after lunch. I get more milk than coffee.
• PopeDotNinja 6y ago
  ~10 cans of diet soda per day.
  • dawnerd 6y ago
    I'm with ya, it's horrible but gets the job done. Can't stand coffee and tea just takes too long (I do enjoy it though)
    • gremlinsinc 6y ago
      Same, used to be reg. soda though. Now it's diet Barq's, diet cherry pepsi, or diet mtn dew. Lost a bunch of weight switching to diet a few years back.
• AndyMcConachie 6y ago
  Regularly 2 cups a day. One after breakfast and another after lunch.
• tekkk 6y ago
  Once upon a time, I drank about 3 a day. Then I would start to get headaches after a month or two, and had to take a break from coffee. Then I started drinking 2 cups a day. Now it took longer for the headaches to appear, but eventually they did. Especially if I didn't drink for a day, the next day headache would probably emerge. Now I drink 1 cup a day. No headaches. And frankly, 1 is enough. It's the same problem with every form of indulgence - it's not about the quantity, but the quality.
• haliou 6y ago
  Used to drink 2 cups a day. 1 after waking up and the next as soon as I reached the office. As coffee affects my sleep quite badly, moved to having only teas during the weekdays and enjoying the coffees at the weekend.
• jrs95 6y ago
  Now that I'm working remote & holed up in my apartment all the time, none. I got some of the DOOM Eternal branded G Fuel for the game launch, and it's strong (300 mg of caffeine per serving...and it's spicy lemonade, which sounds weird but it's delicious) so I have that on occasion in the morning to recover from a night of bad sleep. For the most part been staying away from the caffeine though and I've adjusted to it pretty well. As soon as I get back in the office though, I'll probably be having 3-4 cups a day. Sometimes cold brew, mostly just black coffee. Occasionally I just do tea. Part of it I think is I just have a bit of an oral fixation, so drinking something helps me vape less (I used to smoke) and eat less (mostly sedentary lifestyle unfortunately)
• polyterative 6y ago
  2 espresso, one once awake, one after lunch
• teabee89 6y ago
  I don't drink any. I take power naps if needed.
• mister_hn 6y ago
  3 cups espresso a day
• angarg12 6y ago
  Once upon a time I used to have 6 to 10 (3-5 double Espressos). Nowadays I tend to have 4, 1 double Espresso for breakfast and two Americanos, one mid morning and another one after lunch. Despite what others say I never had headaches or other adverse effects, I just get 'the jitters' if I have more than 5-6. Two weeks ago I quit coffee with my wife as part of an elimination diet and again I haven't felt any side effects, although I do miss the flavour and feel more tired at times.
• pizza234 6y ago
  I drink 4/6 espressos every day. There is no correlation, beyond any doubt, with the quality of my sleep (I've tracked my coffee drinking and sleep patterns for a long time), as long as I don't drink any after a certain time in the afternoon!
• SBCRec 6y ago
  I have done many regimens. My current pre-quarantine schedule was: Morning 1x long black at a cafe near the office with a colleague Rest of work day (plus minus 1 on each item) 2x long black from machine in the office, 1-2x long black with another colleague(s) at a cafe Home (around 5-6pm) 1x long black Current WFH schedule is: 2-5x long black roughly every 90 mins. I enjoy the ritual of making it (plunger) and the warmth. I don't think I get a buzz anymore, but the odd time I do, I love it. I don't get any noticable side effects, and have gone periods 1-4months without drinking it with no adverse effects.
• michalu 6y ago
  I've been trying to stop drinking coffee for a while. I would have two strong coffees a day and a first thing in the morning. First, I was surprised to find it doesn't make me productive at all. I've been tracking my distractibility levels as a measure of my focus (I have a manual counter by my desk) and record my daily times in spreadsheet with notes for those time blocks when I drank caffeine. My distractibility goes up by 100% on average ... Yes, you get an energy and alertness boost but in my case it's funnelled into lack of focus. It's tricky because it works but you lose. Secondly, having black coffee every morning on empty stomach led to some stomach issues that are now gone. I also had regular migraines (turns out migraines are dopamine related - i.e. caffeine) I went cold turkey - headache for days. Then I put up a spreadsheet on the cupboard in my kitchen and made a commitment with my gf to only drink 3 coffees a week, each logged. Now I keep it at 3 a week and I drink them strategically. Instead of going for the coffee first thing in the morning I leave it for the moment, mid day on days when I actually need the boost, instead of ruining my natural energy right in the morning. This makes me super productive. I have no migraines, good solid energy and better focus throughout the day and when I actually drink a cup I really feel the caffeine in my brain (it feels just like a drug) and benefit from it.
• Areading314 6y ago
  I have found strong, loose-leaf tea to give me a much better energy profile than coffee, and it seems to be healthier. There is also quite a variety in different types.
  • spacechild1 6y ago
    I also prefer loose-leaf green tea. To me it feels more gentle, coffee tends to make me nervous and my stomache complains. I still occasionally drink a cup of coffee when I have to go somewhere very early (which for me is anything before 10am) and I need the sudden caffeine rush to overcome my sleepyness.
• sawmurai 6y ago
  About half a liter... more when I work. I love it :)
• tarasmatsyk 6y ago
  No coffee for me, I prefer tea (without milk :D) I used to drank coffee when I didn't have enough sleep or had to go to the office before 10 AM. My body never reacted well to the coffee and it got worse when there were morning meetings. Since I gave up on the office completely I don't need more coffee and drink it maybe twice per year just to enjoy its taste if I am in the right mood. Sometimes I envy people who can have 2-4 cups in a day and be fine as coffee nowadays is too good to ignore it. Anyway, as for me I get too much dizzy from it and feel like a hungry squirrel from the "Over the Hedge" squad.
• perlgeek 6y ago
  None at all. If you're not used to coffee, you need it less.
• sourdesi 6y ago
  Probably 2-3 per day for me. Side note: One of my favorite authors Michael Pollan recently published a short audiobook on the effects of caffeine, some of the history behind it, and his experience going cold turkey for a few months. Really quick and interesting 2 hour listen. It's called Caffeine. Thought I'd share since I found out about his last book "How to Change your Mind" on HN and found it fascinating.
• adev_ 6y ago
  Between 0 and 8 cup per day, depend of the day. - When I'm traveling or on holidays 0. I travel regularly in countries without coffee culture and jet lag with coffee is a terrific mix. - In normal day of work around 5 including 2 in the morning. - In heavy day of work with many meetings around 8. I tend to prefer good technical/design discussions around a coffee instead of endless (useless) PowerPoint session. It's in my experience both more efficient, human and brief.
• toxicFork 6y ago
  I quit a few weeks ago, after switching to decaf a few months ago. I am happy to be able to sleep.
• bootloop 6y ago
  I don't drink coffee. I prefer to sleep when I need rest. But I trink a lot of water. And as I like it cold I am fetching new once throughout the day. That gets me away from the screen and allows me to talk to peers (who drink coffee).
• snypox 6y ago
  I don’t drink coffee at all. I don’t get the hype. It makes some people addicted which is scary.
  • mesaframe 6y ago
    Coffee doesn't work for me too. Sometimes I feel sleepy after drinking coffee.
• DDR0 6y ago
  I don't drink coffee. Or tea. Or energy drinks. I get me enough sleep, such that I'm waking up naturally before work, and then I just… do it. ¯\_(ツ)_/¯
• mfontani 6y ago
  A while back (couple years) I started tracking how much coffee I drank, and (roughly) when. I created a simple Mojolicious webapp, putting data on a SQLite database. I later expanded it to accept/use an "API key" with which I could track my coffee intake, or get how much I drank already and when was my last cup, "simply" by running a simple bash+curl script. The site, instead, displays a neat github-commits-like chart[1] and some recent stats. I have a branch which changes the code to work on Postgres and is deployable on dokku, but I've not yet made the switch to that. I'm still using a mojolicious+sqlite+hypnotoad process running on a cheap VPS. Since I started tracking my intake, it looks like I drank, on average, 3-4 coffees per day: sqlite> select (select count(*) from intake)/(select julianday(max(time_t)) - julianday(min(time_t)) from intake); 3.7864677548175 Here in Italy's northern region, the quarantine started region-wide on the 8th of March. sqlite> select (select count(*) from intake where time_t > "2020-03-08")/(select julianday(max(time_t)) - julianday("2020-03-08") from intake); 4.20309898028925 It looks like I'm drinking a bit more coffee than the usual, but surely nowhere as near as my most intake: sqlite> select date(time_t) as ymd, count(*) as cnt from intake group by ymd order by cnt desc limit 5; 2018-05-16|11 2018-03-12|10 2018-05-15|10 2018-02-07|9 2019-06-04|9 Hope it helps! :) [1]: https://i.imgur.com/c0DqAGO.png https://i.imgur.com/c0DqAGO.png

    • temikus 6y ago
      Not the OP but if you like recording personal statistics, you might like http://reporter-app.com/ http://reporter-app.com/. I've been using it for personal experiments a bunch of times (like measuring stress levels).

• Antoninus 6y ago
  3 cups a day. 1 after waking. 1 before standup at 10am. 1 at 3pm. More ruins my sleep.
• senectus1 6y ago
  not a programmer, more of an admin :-P but, 4-8 cups of black no sugar coffee a day... 2 in the morn, one after lunch one at about 3pm. that is a typical minimum. Any more is typically because I didnt get enough sleep (gaming watching movies working etc). I try hard to not do that now, but it sneaks in.
• robjan 6y ago
  I used to drink very little but then the office reduced the friction of getting a cup of coffee by installing a machine which grinds and brews espresso. Now I am on 3-5 cups per day but slowly reducing my intake.
• smcl 6y ago
  One after breakfast, one after lunch. Any more and my nerves feel jangly
• MrDresden 6y ago
  In my experience being in the office causes me to drink more coffee due to the social aspect of it. I got my self espresso machine last xmas and am now only having 2-3 espressos a day where before I was perhaps having 3-5 big mugs of strong coffee.
• chad_ocho 6y ago
  I take some vyvanse in the morning along with a tall boy of Starbucks espresso mocha and I’m good for the day
• roydivision 6y ago
  None. I have two at most cups of caffeinated tea in the morning on a work day, and that’s it for the day. I have a very low tolerance for caffeine, a little goes a long way. And I’ve fallen into the trap in the past of starting to rely on it, which turned out badly, stress, sleep deprivation, etc.
• Yetanfou 6y ago
  Real Programmers Drink Tea, have you not heard? Anyway, 1 a day, max. Tea on the other hand is not counted in cups but in litres, the cup I use holds about half a litre. I go through 3-4 of those on a good day, 1-2 in the evening. During the day it mostly contains a darker fermented tea variety - I buy it by the kilo - usually labelled 'Ceylon', often with some form of horse on the packaging and a horse-related name even though they're different brands. In the evening I often have some green tea, either plain green or jasmine or with star anise. For all-night hacking sessions I like to use a mix of jasmine and Lapsang Souchong (smoked tea).
• captn3m0 6y ago
  Zero. 1-2 cups of tea (usually black, but sometimes Chai because my flatmates prefer that). Guessing my average per day would be 1.5 cups or so.
• deleted 6y ago

• fanf2 6y ago
  I make a 1 litre cafetière of coffee most days, which makes three mugs of coffee. I use about 50g - 60g coffee per cafetière. I have a Bodum Columbia which is insulated to help keep the coffee hot for a couple of hours. And I try not to have more caffeine after my morning coffee.
• scott10 6y ago
  Pre lockdown:double-shot when I wake up wile the Keurig was heating up, then a cup of coffee. 5-shot latte on the way to work, sometimes a 4-shot afternoon latte. I gave up coffee once in the 90’s for a month. I felt rundown and was very congested; I thought I had the flu. One day walking through the breakroom I was walking past the coffee pot and had to have a cup.i felt a bit better and went back for another. I felt better still. After 5 cups, I felt fine and my congestion was gone! I never cared after that how much coffee I drank as long as I got enough.
• nextweek2 6y ago
  10-12 on a work day, have done for 20 years. When I'm off I end up having 3-4 during the course of the day but certainly feel more sluggish on those days. I took a break for 4 months a few years back (to see if I could) and really struggled to keep my eyes open, even with 8 hours sleep on a normal day. I don't have any issue sleeping and no negative effects from large volumes of coffee. I drink high strength coffee. This is also probably offset because I drink a lot of water during my day as well. Again probably 10+ pints of water during the course of the day. I'll drink water no matter what I'm doing. I can't fathom how some people go hours without water, to me it's the most important thing for my brain function.
• mstaoru 6y ago
  I prefer extremely dark, almost charcoal roasts (which actually have less caffeine) of Colombian or Indonesian origins. Roast them myself in a pan over a gas stove. I can drink 3-4 mugs of Aeropress coffee, 17g beans per cup. This, and smoking a pipe of a good English or Oriental tobacco, absolutely heaven.
• danaris 6y ago
  None. I've never liked the smell/taste, and on the occasions when I get some caffeine from a different source, I find that, at most, the effect I get from it is a bit of jitteriness and a headache later on.
• bmn__ 6y ago
  In https://daringfireball.net/linked/2017/11/13/coffee-cardiovascular-disease https://daringfireball.net/linked/2017/11/13/coffee-cardiova..., Gruber writes: > I like that 5 cups of coffee per day qualified as “moderate”. That’s right around what I consume. My immediate thought was "that's crazy, if anyone I know were to drink that much, he'd get mighty uncomfortable or even ill with shaky hands, a punishing heartbeat and heavy sweat". I told my colleagues. One replied and pointed out that the Americans dilute. All the measurements in the comments so far are useless for drawing a conclusion. We should use milligrams of caffeine consumed and the body weight to have a sound basis for comparison.
• BrandoElFollito 6y ago
  I like the taste of coffee but is no impact on my body: I am not more alert, I can go to sleep right after a coffee and I have no problems with sleep. I usually drink 4 or 5 Nespresso cups. Sometimes 6 or 7. I can go without anytime, but I would then sometimes miss the taste and the whole "sitting in the hamac/couch with a coffee"
• kevinherron 6y ago
  I drink 1 cup every morning, and sometimes part of a 2nd cup after that. When I was still working in an office I’d often have a double espresso after lunch as well.
• photawe 6y ago
  I thought I drink too much, but reading the other answers, seems I'm on the safe side :D I drink 3-4 cups/day (each cup, with one teaspoon of Amigo coffee and quite a bit of milk :P)
• trm42 6y ago
  I've had about two cups of coffee in my whole life but I'm addicted to tea. Especially good quality senchas. At work place I was drinking about 2-4 x 450 ml per work day. Now at isolation home it's 2-3 cups (maybe 200-250ml per cup) every work day. Not sure, if the reason for lesser tea consumption at home is because my 450ml pot is at the work place or because I have better concentration at home and less distractions compared to the noisy open office...
• ClikeX 6y ago
  3-5 a day. Usually 2 in the morning, one right before lunch. Sometimes I'll do one in the afternoon and/or a decaf after dinner.
• markpapadakis 6y ago
  I never had coffee. I drink Diet Coke and I enjoy tea ( I have some once every week or so ). I have been writing code for over 25 years now, and I never felt that I was missing out but then again not sure I’d know either way.
• ulisesrmzroche 6y ago
  Probably like a gallon altogether from all sources, sometimes more. Cheers me up knowing that soon I’ll be so intense I actually think the jittery feeling is the best part
• downshun 6y ago
  Minimal. Even with the increased alertness, it steals away that productivity from the next day, often resulting in a net loss due to lack of proper sleep. It increases alertness, but reduces focus. Reminds me of a friend's remark on why he quit pot: "the scary part was it really convinced me I was productive in my day when in fact I was not"
• cafard 6y ago
  I drink my real coffee at breakfast: two strong cups of a dark roast. At the office, I will get a couple of cups of cafeteria coffee in the morning--I don't regard it as serious coffee, just as something to sip in the course of the day. Over the last six weeks I haven't been to the office, so the two strong cups at breakfast have been all I have.
• kleer001 6y ago
  Zero. My body doesn't like coffee. Trust me, I tried, for a good decade. It used to be good between me and coffee, but not so much anymore.
• sethammons 6y ago
  Zero. While coffee smells nice, it all tastes like ash. No, it is not burned; I’ve had pros coax me into a sip of the best they know. Ash. Also, I get tired when I take caffeine. The best pick-me-up for me is a light, high protein snack.
• RickJWagner 6y ago
  How much coffee do I drink as a programmer? All of it. Programming is the only job I have.
• CM30 6y ago
  None. For whatever reason, I just don't care for the taste of either coffee or tea. That isn't a health thing either, I simply csn't understand the appeal of these types of drinks and have never liked the taste of any I've tried.
• pxhb 6y ago
  A lot - around 6-8 cups/day I have one large mug of coffee first thing in the morning (~3-4 cups). I then have a mug of half-caff coffee in the late morning, another mug of half-caff in the early afternoon and occasionally an additional mug in the late afternoon. I have gradually been cutting back on caffeine, mostly by slowly transitioning to more half-caffeine coffee.

  I make a cup using full immersion method in the morning. If I am still tired after lunch, I might make a second cup. That is it, I don't go over 2 cups. I try to make the second cup before 2pm my time.
