I have so many friends that get 4-5 hours of sleep on a good night, and we're only seniors in high school. Personally, I usually goto sleep between 10-11 and wake up at 5, for 6-7 hours of sleep on an average night. Like tonight i'm about to goto bed, probably wont get up till 6, so that's a great 9 hours of sleep. How much did u usually get during high school? Do the hours increase after you graduate and go into college? Then enter the work force?
