With me I have a lot of trouble falling asleep. But once I do I sleep for around 12 hours or so. I wake up tired still. It sucks. I am on so much medicine not just for bipolar but other things to. My family thinks I am on too much stuff. Most of the time I am like a zombie and have memory problems to. I think the meds are messing me up more then the disorder itself is. Don't know for sure.
