mance anxiety
"I've had multiple bad experiences with public speaking. Sometimes I would make it through the entire presentation, depending on how long it is, but I would always get so nervous that it would cause me to have dry mouth, and it would feel like my throat is starting to swell from my heart beating so fast that I would not be able to finish my speech. My doctor prescribed me propranolol, and after taking about 40mg 1 hour prior to my presentation, it was like magic! I went in front of the class and spoke without hesitation or any signs of nervousness. I felt like I could've talked to the class during the rest of the time there if I wanted to. I only take my prescription for presentations so I won't become immune to them."
