Propranolol
"A year ago, I was asked to read at my friends wedding & since the day she asked me I have been terrified as I usually experience an extremely intense heart beat like it's going to jump out of my chest, I can't regulate my breathing so find it hard to even get a word out, & I also experience dizziness like I'm about to pass out. I took 20mg the night before to test how I would react with it, 10mg about 1.5 hours before & another 10mg 45 mins before. I've never known anything like this. I read my speech with clarity, I could even look up and make eye contact with the bride & groom. My fiancé was gobsmacked. Usually he has to try and calm my nerves, all night he kept saying how amazing I did. I have a new found confidence now."
