I have been finding that Propranolol helps a great deal for anxiety and PTSD. I have both along with dissociation. Since I started that medicine I stopped the klonipin. I haven't had any success w/ any other medicines, too many side effects. I just read an article by the Mayo clinic about Propranolol, but I can' remember if it was for PTSD or anxiety. I was glad my P-doc was so up on the current meds for PSTD and Anxiety. You would have to check with your doctor.
