How many hours of sleep do you get/need per night?

An adult needs about 8.5 hours of sleep a night. I am a strong believer in the "sleep debt" theory, which is that when you get less than your required amount of sleep, if just builds up as a debt (to a point). I tried it during the school year (high school) last year. For the first 5 months of the year, i had gone to bed at 12 or 1, and woke up at 630. i started going to bed at 10-11 (eek!). one day after a few months of that, i got up and was COMPLETELY refreshed, and the rest of the day, was just fine, and i didn't feel the slightest need to sleep till midnight that night. Try that, it takes a few months of getting to sleep early, but then you feel great.
