Propranolol
"I have mild social anxiety and low self-esteem. Whenever I have to speak in front of a group of people, be it a short introduction or a 15 minute presentation, I start blushing uncontrollably, my heart wants to pound out of my chest, and my voice starts to tremble. It's absolutely humiliating, especially when you're in graduate school and your peers speak competently. I tried out 10mg of propanolol (I'm a petite 5'1") an hour before my presentation today and was stunned. I not only did not feel terribly nervous, but I was CALM - almost lethargic. When I walked up to the podium, I could feel my nerves emotionally, but my body gave no unusual responses. Unfortunately I did get mild chest tightness a couple hours afterward. Worth it? Totally."
