I've read on resetting one's biological clock and clearing my mind before bedtime (and I do most of the things there, using F.lux, being physically active mostly every day), taking melatonin (0.5-1mg), BUT...
I still don't want to go to bed at 2am, when I should. I feel I still have energy, and indeed get work done, and end up going to bed at 5am. Sleep is not interesting to me. Btu then I wake up at 11, can't fall asleep again (or if I do, it's after 90 minutes - a sleep cycle - then I sleep another 90 minutes and it's 2pm), so I only get 6 hours of sleep. Bad.
I don't drink caffeine or eat chocolate or sugar, and I follow largely a slow-carb diet. I've been tracking my sleep for more than two years, and I've never woken up refreshed, ready to jump out of bed; just "ok". I use earplugs and an eye mask, and my bedroom is pretty dark (though not pitch dark) and cool.
The problem seems to be one of discipline, less so of sleep hygiene. How do I just put myself to sleep at 2am, and get 8 hours of sleep and be productive (and in sync with the rest of the world in my time zone), when there's so much interesting stuff I could be doing after 2am, and while I probably have a non-24-hour sleep/wake pattern ?
