I've had a lot of trouble with nightmares in the past (I used to have panic attacks in my sleep) and I was on Remeron before the PTSD therapy that made most of them end. There wasn't an increase in nightmares at all, just dreams. I had a sleep study a few years ago that showed I have about 20% of normal REM sleep so dream very little but on Remeron that was different.

Remeron was this magic medicine for me though. I was put on it while it was still really new and was on and off it for a number of years, a lot of them before I was diagnosed. I know it makes no sense for an AD to do this but I am pretty sure that it worked as a mood stabilizer for me. I think it got me through grad school and into a job and established there and then I changed meds and the bipolar became a serious problem.

How is the Rexulti going?
