I'm not diagnosed officially with dysautonomia but doctors have been treating me as such and I generally consider myself as having some kind of dysautonomia due to symptoms like quick fatigue, slow systemic updates to postural changes, vomiting from a relatively minor exertion, always being tired, other things. My BP is about 110/70 normally.
I read up here before trying Prazosin, but because of the compounding effects on fatigue of extreme nightmares and sleep disturbance plus daily anxiety related to CPTSD, which I also have, I decided to try it.
Freakin' miracle drug so far. I'm pretty amazed. I've only been on it 2 nights so far, 1mg at bedtime, but they are the 2 best and longest nights of sleep I've had in ages. I do sleep for about 14 hours when I take it, which might be an issue after I get past the point of actually feeling catching up on rest, but maybe a smaller dose at that point will resolve things (assuming they make it in .5mg).
I mostly wanted to say, I am glad I tried it in spite of cautions. It will affect different people differently, but prazosin may be more worth a chance for dysautonomia patients than it seems. You are not guaranteed to have effects this good, but it turned out for me to be very worth it.
