I try to get to sleep at around 10PM but obviously in this industry, it can be at all hours of the morning before you get some sleep.
It is a proven fact that the best way to get to sleep early is by watching Charlie Rose around 11:00. I usually go to bed around 4.
I don't really sleep, I don't think many internet users do, due to the fact that the internet is timeless in itself
I'm a night person so work on my websites until the early morning hours .. anywhere from 5am to 8am and then crash.
I go to sleep around 3-4AM and wake up about 10:30PM. I work better at night because when everyone is sleeping I don't get distracted as much.
