I am looking for folks whop have been prescribed guanfacine for PTSD or anxiety. I suffer form both, and have been suggested guanfacine on two separate occasions, but so far I have decided not to go the medicated route. I still want to know what guanfacine is like if I do get worse all of a sudden. Does guanfacine have any bad side effects? I am hoping someone can say more about this.
