I had to find a way to live without the Prazosin. Switched it up to a natural diet and writing just before bed to help with the nightmares. The daytime flashbacks, I just forced myself to deal with. It isn't the best path and sure as hell isn't easy. Took a lot of time for me to get to a point of stability. Occasionally, I would take an anti-anxiety when they would be bad. It would at least help with the panic attacks that followed.
I couldn't keep taking the Prazosin because I have a naturally low BP and it just wasn't worth it to me, even though it helped a lot.
If you vote not to go back on it try to make sure that you have your T on call a bit more and maybe schedule meetings closer together. You might need to get through it like that. If you vote to start up again, just keep a good eye on your health.
