Hi, haven't had panic attacks in years but they came back this week. I've been on 200mg sertraline (zoloft) for 5 years and the first 4 years I felt they helped but I think they've stopped working. Not going off them yet per doctor's advice, but the other day I got prescribed 10mg propranolol and I'm supposed to take 2 or 3 when I feel panic coming on. I've just taken 2 (20mg) and I am very nervous as I have emetophobia and that is the main source of my anxiety.. I am afraid these will make me nauseous or vomit. Even then, I just want physical anxiety gone. I just want to know everyone's experiences with the specific dose of 20mg or even 30mg. Thank you.
