My usual for most of my life is to sleep 2-3 hours at night. But when I'm depressed it turns into 12-24 hours asleep, and still tired when I wake up. I'm now on meds which help somewhat to regulate my sleeping. Trazadone was very good for sleep, but the pdoc took me off it in June. Now I take Nozinan, which doesn't work as well. I now go to sleep after midnight - sometimes 2 am and sleep until noon. I'd rather go to sleep earlier and be up in the morning. This is one of the things I need to ask my pdoc about.
