For me this is really simple, i usually goto sleep at 11pm-12pm and wake up at 7-8am without an alarm or anything and i feel great, so i figure that 7-8hours is optimal for me. I try to keep that routine during the week, because if i stay up too long only 1 night, it makes it more difficult for the rest of the week. I am more of a morning person anyway, rarely been very productive late at night.
