Gentle hugs to you as you struggle with this. I have somewhat of the same problems as well. I may sleep for 4 hours after the Klonopin wears off (have you tried that?). It's a hard plight that many people with bipolar face.

The only suggestion I have is try to get yourself in some sort of routine. I used to be up at all hours of the night and day, and now I have finally gotten my sleep down to some sort of routine where I can have an afternoon job for a couple of hours a day.

I am sorry that wasn't helpful, but I know how tough it is. Even now writing this I feel drowsy after sleeping almost 9 hours.
