I was wondering how important is sleep. I sometimes get to bed to real late, especially friday nights. This past friday, I had a great workout, but I went out that night. I didnt get to bed till like 6am. But I also slept on and off till about 4pm. All in all it was about 8 hours, on and off. Does it matter WHEN I go to sleep, aslong as I am getting 6-8 hours of sleep?
