One thing I realized with poor sleep, it makes my mood changes worse. I hope you get solid sleep soon, I imagine it similar for all of us with bipolar. Put on happy shows before bed.

I switched from Melatonin to benadryl (just 25mg, 50 if im frigidity. Anymore and it makes me pee 100 times) and only take the Melatonin when im struggling with long periods of bad sleep. But the Melatonin always made my dreams worse and its the only time I experienced sleep paralysis too. Never want that again.
