I actually have a diagnosis of "insomnia due to other mental disorder" because my pdoc thinks it's part of my bipolar. So I'm on a snootful of meds to make me sleep, among other reasons. Even so, I've been having trouble getting to sleep before 2 AM lately, probably because I'm just a little hypomanic and have been for about three weeks. I sleep enough, I just don't seem to be able to do it at the "proper" time. I also wake up at least once a night.
