When I'm manic I rarely sleep at all. Sometimes 2-4 hours sometimes no sleep whatsoever for several days and at that point I get psychotic. If I sleep 6 hours when I'm "normal" I consider myself lucky. When I'm depressed I have no problem sleeping 12 or more hours and I have a real hard time getting up in the morning. Some mornings I get up just to take my daughter to school and the baby to daycare and go home and go right back to bed and stay there all day.
