I wish there was a better way to tell which sleeping position is truly best. because all the articles I've seen say "these are the most common positions, X is best… except for these things," which to me, has translated to "We have an opinion, but we don't really know anything,".
what I do know is this:
like what >>133753 said.
>Caffeine affects you sleep if take it fewer hours before bedtime.
>alcohol is a stimulant, and then a depressant. It'll get you going and then make you sleepy, but it's not a good kind of sleep
>Not everyone can power nap, but if you can get into a deep-trance meditation, it'll work just as effectively.
>your bed matters too. firm is ideal for support, but not all of us can sleep on straight-up-wood. springs last longer than foam. if you're fat or just plain heavy, your bed will break down faster, no matter what you use.

If you slept really long and still felt tired getting up, you're getting too much sleep. you're getting 9 hours so you should be fine.

how long have you been doing this!? You might have chronic sleep deprivation, 3:30 to 8:00 (ew) is only 4.5 hours! How long are your naps? If you've been depriving yourself, your body will want to compensate, it's the reason you go twelve hours when you go to bed early.
>And one of nature's rule is take a nap in the middle of the day or everything pisses you off
this is true. every since I started taking naps after work, I've felt less tired getting up in the morning.
