I wonder how much coffee plays into this. I've yet to meet someone who sleeps consistently more than 8 hours per night who feels the need to drink coffee. edit

I wonder how much coffee plays into this. I've yet to meet someone who sleeps consistently more than 8 hours per night who feels the need to drink coffee. edit: 8 quality hours of sleep, e.g. you wake up and you're not tired.

On the flipside, it's kind of crazy that there are people who are able to function consistently with very little sleep. A friend of mine says that if she gets eight hours of sleep, she feels incredibly groggy. But five hours? Perfect. She's been like that her entire life. I was astounded. She directed me to Ying-Hui Fu's study of DEC2.

I'm one of those people. When I'm in the habit of drinking coffee, regardless of how much sleep I get, if I miss my scheduled caffeine I get withdrawal symptoms- sick to my stomach, headaches. I'm currently most of the way through slowly on my caffeine intake, though, and it's been going well- it's just abrupt withdrawal that causes problems.

Hi. I sleep 8.5h a night and I need coffee. Nice to meet you.

It depends on how much more than 8 hours we're talking about. Consistently oversleeping, especially 10+ hours a night, can be indicative of some potentially serious problems that either already exist or may in the future. Rather than making someone feel well-rested, it often has the opposite effect: confusion, lack of energy, sluggishness, etc. due to a poorer quality of sleep in general. I'd imagine that self-medicating with lots of caffeine is a pretty natural response for most people in that situation even though it doesn't actually solve the problem.

> quality hours Yeah, that's the important part. I can sleep 10 hours and seem to get nothing out of it and still need coffee. And the coffee may be part of why I'm also not sleeping well. Not a good loop to be in.

huh? I sleep 8 hours a night and I definitely "need" coffee. It's a chemical thing at this point.

I have sleep apnea. I need 10 hours of sleep and coffee in order to function.

That's me. Genetic daytime sleepiness is a thing. Modafinil has been a lifesaver for me. Also, you have people with inherited dopamine management issues. Adhd aside, dopamine regulates internal clock, so delayed sleep phase is also a real thing. F.lux, blindshades and enough sunliht help, but just to a certain extent.
