I also took it for nightmares and still have plenty of it in my cupboard. I stopped taking it because it dropped my blood pressure pretty low and was affecting my ability to work. Therapy has helped a lot with my nightmares and anti-anxiety meds at night have helped a lot with them too. I also stopped taking it because my new pdoc had never heard of prazosin for PTSD and she didn't want to prescribe it. But that was okay, I found other methods to get rid of the nightmares through therapy, etc.

It works pretty well, IMO.
