Can't sleep due to PTSD nightmares, need advice

I dont know specifics. But I do know there are meds that will stop dreams. I too cannot sleep for longer than an hour at a time but I think it has more to do with my chemicals and less to do with my PTSD. I rarely have nightmares bc I dont sleep deep enough.

seconding the prazosin, it changed my life for real

I am on Prazosin for PTSD and nightmares. I will say, yes, it helps me a great deal. 4mg nightly. I haven't been woken up by kicking and screaming since I started it
