I take prazosin, also. It took a bit for it to really start working for me, and a couple adjustments. But now, it works pretty well. I called my pdoc a week and a half ago, about upping it temporarily, cuz I got triggered pretty bad, and that small increase is doing well. Main side effect that can be an issue at higher doses is slowing pulse and lowering blood pressure, if I remember correctly. Try to give it a chance, I hope it ends up working for you.
