Meds wise, I think my gabapentin and Latuda help a lot.

I've found my sleep improved a lot when I gave myself a set bed time. I go to bed at like 9pm every night. I don't allow myself to get up and get involved in something either. No TV or anything. If I get involved into something, then I catch a 2nd wind and am up at least half the night. Took awhile to get into the routine, but it was the best thing I ever did sleep wise. Now I find I can still get 6 hours of sleep even while in an episode.
