If you mean sleep in a dorm at school, I'll have you know that didn't help either.

First class of the day was at 730 and what that really meant was rolling out of bed at 725 still in my clothes from last night and trudging over to the building next door where I would be marked present and immediately fall asleep in my desk. The first class was utterly worthless as far as I know and I learned not a thing. Shower and change of clothes and actually starting my day happend during breakfast break later.

Part of the problem, imo, is that quiet time in the dorm started at 1045 but was poorly enforced so often it was impossible to get to sleep till 1130 or later.
