I'm impressed with you people who only get a few hours of sleep a night and live. I need 7-8 hours a night or I just plain quit functioning. So I go to bed at about 11pm, am usually asleep within 15 or 20 minutes, and then I wake up around 7:00am the next morning. That way I'm ready and raring to go if I have an 8am shift the next morning. If I don't, well... I'm usually "naturally" up by 7:30 anyway, so *shrug*

Sleeping in gives me headaches. I have to be really on top of my sleep schedule.
