About 7-8 hours a night, plus usually a 30 min morning nap after my workout (and my shower of course). Always a nap or two on the weekends too - not because I'm sleepy necessarily, but because they feel great.
8 to 9. I wish I could be productive on less. Last night I got 11 hours (could have slept longer too)....I stayed out late on Thursday night and I guess I was still making up for it!
