Propranolol
mance anxiety
"I've always had an abnormal and extremely strong physical response to public speaking. My heart will beat like I've just sprinted 100m, my voice will become so shaky that I can barely speak, and the sense of panic scrambles my mind so much that I don't even know what I'm saying. Having to introduce myself at a meeting triggers something approaching a full-on panic attack. It's extremely unpleasant and very embarrassing. Psychologically I don't fear public speaking; the physiological reaction is just abnormal and disproportionate. 

Propranolol works wonders for preventing the physical response. I take 10-20mg 1-2 hours before exposure and can speak normally in meetings, etc."
