I keep hearing about people who used to have sleep schedules like I currently do (4 to 5 hours during week, 10 on weekends), and all of them say that I would feel better on 7 or 8 a day. I thought, "great -- I'll give that a try!"
in reply to Hours of sleep I get on an average weeknight
However, I ran into one big problem. I could not go to sleep. I would get 8 hours of sleep (say, 12-8am). I would wake up, go to class and work, do my homework, surf the Internet; and, finally, try to go to bed again around midnight. But, I couldn't. I would lie in bed with my eyes closed until 4am or so. No matter how hard I try, sans the use of substances, I could not achieve a stable 8 hours-a-day sleep schedule. Doing the 8 hours a night thing would mean my schedule being constantly rotated as my body wants to stay awake for 20 hours after getting 8 hours of sleep. Only after going 5 days on 20-25 total hours of sleep can I actually crash on the weekend and get a good night's rest.
Maybe this will all change once I leave college, but for right now I am a slave to my screwed up circadian rhythm (or, lack thereof).
