Propranolol
"Absolute miracle - I cannot believe it. I take only 10-20 mg as needed, and it basically shuts off the fight or flight response.  Those sudden adrenaline bursts followed by total fear and panic just no longer materialize.  In fact your entire body will probably thank you for the stress relief.  Propanolol has given me tremendous confidence with virtually no side effects.  This coming from someone who has thought it might be better to get hit by a bus than have to attend weekly staff meetings.  More effective than alprazolam and without the side effects, from my experience.  Doctors need to look at propranolol as first line treatment for anxiety!"
