mance anxiety
"If you have serious performance anxiety, propranolol is an absolutely great help. I used to worry for weeks about any sort of public speaking/performance, even when it was as short as a couple minutes in front of 15-25 people. By the time I actually got up to perform, I had overthought it so much that I was panicked and my heart raced, face turned red, voice shook, etc. I took 20mg of propranolol (10mg 90 minutes before, 10mg 45 minutes before) before a presentation and I felt pretty calm leading up to the presentation.  I was even calmer when I started presenting and presented better than ever before. I honestly don't think ill ever worry about public speaking again."
