Minipress, otherwise known as Prazosin, has helped me. It's off-label for PTSD & was 1st prescribed for veterans. Have been taking 1-2mg a night since last summer, but nightmares have recently returned.... psychiatrist said ppl take up to 6mg & that 1 or 2 mg "is nothing". One side effect- rather, effect, as "side" effects are just that, effects- is inability to remember any dreams at all, at least at first, though I slept for the 1st time ALL night since -when? Can't recall that far back. No hangover. Apparently, nightmares cause physiological stuff that awakens the body.... but Minipress lets ppl sleep an additional- can't rem., 82? 92? minutes a night... Agreed on the Klonopin (wow, friends have horror stories), & the benzo w/draw & rebound anxiety, etc. Am at 2mg Xanax a day. This @%*^ is addictive. Uncool.
