I also experience that high anxiety especially if I go out at nite with friends. It always seems like I am overstimulated. I take a beta blocker as well. Mine is for high blood pressure and the anxiety. I was told people that are performers etc will take a beta blocker before a performance because it stops some of that adrenalin from running thru the body.I do know you should not abruptly stop a beta blocker

Yes I do know what you mean..its sometimes seems like the adrenalin is just pouring thru my body. Thats when I need to calm myself, be alone...!

Its a good idea also to lay off the coffee, soda etc..even chocolate...anything that has caffeine. I'm bad with this as I love my coffee in the morning and it does wake me up. However I really don't drink it much during the day
