to a post i read a few pages back.
im on betablockers (propranolol) and they do stop the surges. it takes about 20 inutes to work but you just feel a bit calmer, looser, not as tense. your head feels fine, it doesnt alter your thinking all as they do is slow your heart rate down, but if you have a had a bad time recently with jazzy heartbeats(haha!) then beta would work well.
