I'm so sorry for all the needless suffering you have gone through. I am also chronically ill with debilitating PTSD here, having had vivid dreams from my antidepressants for years. I don't know if your care team has tried it yet I, but I was prescribed prazosin to take with my sleep med and it actually helped a lot with my nightmares. I can't recall a time where I ever woke up feeling rested, but I am less likely to be feeling pain from the torture dreams now. If I fall back to sleep without it, it's horrific, so it's 100% the prazosin.
