mance anxiety
"I have a severe phobia of public speaking and major physiological signs and symptoms when doing so.  I would have a pounding heart, sweat, shaking hands, and a trembling voice, and my mind would even go completely blank.  In my career, I had to speak in public on a regular basis and I lived in fear of each speaking event.  I was prescribed propranolol to take an hour before I had to do any public speaking and it helped me out tremendously.  I had no physiological symptoms at all while speaking.  It is a miracle. I highly recommend propranolol for this indication."
