i am on propanolol for over 2 years now, for a mental condition, but it does help my palpitations from the other meds, i'm on 9 different meds, i know the propanol works for me because i never felt as good on anything until the propanolol was introduced, it stopped my migrains and i now it was because of the propanolol, as the doctor who prescribed it at the emergency room said there were more studies with a success rate study where propanolol showed much promise for migrains. i forgot to tell you i was in the emergency room for a migraine too, i used to have to go to the emergency room alot of migrains and all they would give me was imetrix which i hated it would knock me out for days.-avlady
