I've been getting between 2 and 4 hours of sleep the last 4 nights. Normally on a good night I get 6. I don't feel tired.But I've noticed when I don't sleep my blood pressure goes up too high. I talked to my pdoc about it and he suggested I try Ambien..well that didn't work so I guess I'll just live with it. The only time I really get much sleep is when I'm depressed..then I don't want to get up and can sleep 12 hours or more.
