How much do you sleep at night?
leonroy: The way I figure it is, some days you work harder and need more sleep, some days you need less. So I try to be like a machine: I'll wake up at 7am and go to sleep when I'm tired.This results in me getting about 6-8 hours sleep a night - and no sleeping in on weekends! It throws my pattern completely out of whack.As a previous poster said, the most productive hours for a hacker are the wee hours of the morning, when the wife/neightbours/kids piss off and let you code - but I think it's important to keep your waking hours as closely tied to sunrise/sunset as possible - it's all a compromise and one size doesn't fit all.
