Recently I've learned that half of the people are slow caffein metabolizers. The caffein stays longer in their system and it might negatively affect their sleep. Considering how many people drink coffee, I think a lot of people are affected by this.
- xen2xen1 2y agoFound that out the hard way twenty years ago. The stated half life is NOT for me what they say.
- b800h 2y agoYep - raising my hand here. I've completely given up caffeine (including decaf, which isn't totally) because after I got a Fitbit, I realised that my morning coffee spiked my heart-rate to 120, and kept it thereabouts, slowly dropping to normal overnight, after which I'd start again. A genome sequence shows I'm a slow metaboliser (I expect more will show up with more research). I feel terrific now.
- zemvpferreira 2y agoSlow metaboliser here. Also possibly more prone to caffeine addiction than most, according to said genome sequencing interpretation. I need to cap at 2 espressos per day before noon at most, or I start suffering side effects like poor sleep quality. People really need to reframe their coffee consumption from food to drug and understand their own usage and effects of said drug.
- b800h 2y agoPlease try quitting entirely. My cold turkey took a week and a half and involved intense muscle pain (going from drinking a coffee and a tea each day). I believe the caffeine was building up in my system, although I could be wrong. I strongly recommend Barleycup as an alternative morning cuppa.
- zemvpferreira 2y agoI appreciate the recommendation and will try a period of abstinence this summer, at least. I have quit before, but I find it very challenging to stay away.

- roywiggins 2y agoI suspect I am an unusually fast metabolizer, since I can be tipped over into very nasty withdrawal headaches extremely easily, even when my baseline consumption is a couple of smallish coffees in a day. The only way I've found to fix this is to get almost completely off it, which as you might imagine I find very difficult to do, since I have to step down very carefully.
- shrimp_emoji 2y agoMy withdrawals only kick in on the second day of no caffeine. Also, I feel a cup of coffee on the day I drank it and the day after (with no additional caffeine). :D I guess I'm turbo slow. Although I didn't use to be...
- roywiggins 2y agoFor me it can happen in less than 12 hours, which can mean overnight. It's not a great time!
- BossingAround 2y agoSounds to me more like you consume _a lot_ (therefore have a very strong physical dependence) rather than having extremely fast metabolism. Alternatively, you might be prone to migraines, and thus are sensitive to headaches of all kinds. That's me, I truly hope that's not you (wouldn't wish that upon anyone).
- roywiggins 2y agoI promise I don't. I can be on a teaspoon of strongish instant coffee twice a day and it still happens sometimes (though it's worse when I'm drinking more of course). It can happen literally overnight, even when I'm on a steady intake. The headaches are reliably cured within maybe 20-40 minutes by application of more caffeine, so I don't think they are migraines.
- istjohn 2y agoI'm not a regular drinker and even a coke after 11 am means I'm going to have a late night. It's frustrating how often there are no caffeine-free diet soda options.
- shard 2y agoI've learned to drink coffee only in the morning. If I drink coffee any time after 12PM, I'm not going to get much sleep that night. Therefore I have limited my coffee intake to medicinal purposes (i.e. as needed in order to stay awake).
