Prazosin
"It really did help with my nightmares. (And lowered my blood pressure haha). I used to has nightmares almost every night and I have only had 3 on the 7 months I've been on it. My boyfriend thinks this is the best medicine ever created because now we can sleep peacefully. Didn't really help me fall asleep but didn't keep me awake either. And when I slept I would sleep though the night with no nightmares. Just really weird dreams."
