Sleep has become problematic for me too since about mid-March. Every year I go through the same thing: I become hypomanic, start messing with my meds, and then have trouble sleeping. Lack of sleep = increased mania. Increased mania = more messing with my meds. It's a vicious circle.

Now I'm sleeping 9-10 hours some nights, and 4 hours on others. I also go to bed very late and wake up several times a night. I'm not too manicky right now but feel like I could slip back into it if I'm not careful. Welcome Spring! LOL.
