Propranolol
"I get situational panic attacks in high stress meetings or interviews - these started a few years ago.  



My doctor prescribed me 10mg of Propranolol to take 10-30 minutes before meetings, speeches, etc. This calms me down, stops me worrying about the possibility to have a panic attack, and makes me a much calmer person.  Having a pill on me at all times in case the situation arises has given me such confidence that I won't have an attack now that I rarely get them anymore."
