How much do you sleep at night?
timwiseman: Personally on a normal week night I sleep for roughly 5 hours, and then on Saturdays and Sundays I usually sleep for 8-9 hours, so my overall average is around 6 hours a night.I frequently wish I could sleep more and feel tired long before I go to bed most nights, but I do not take it to such an extreme that I believe it truly reduces my effectiveness.  Of course, that is my subjective thought and I have not tried to precisely test it.
