During the week I try to be in bed at 11:00 PM and I'm up around 5:30 AM. On weekends I'm lucky if I sleep an extra two hours - even if I've done a gig the night before. I've gotten acclimated to rising early.
BTW,My hours are a complete turn around from when I was a full time musician. I now get up most mornings earlier than I used to go to bed !
