I think they are a brilliant tablet because they work so quickly, I think once they have helped the physical symptoms your mind rests a bit easier anyway, I was going through major panic the other week, thought I was going to die but Propranolol worked for me, i'm allowed to take upto 80mg a day but i'm glad to say i've been fine for a good two weeks and not had to take any Hope you feeling better soon too Anx Mum x
