Propranolol
"Isopropranolol is magic. Im a senior biochemistry student (straight As). One problem: during presentations,I shake I blush i have this huge blank in my head and don't even remember what i'm talking about. On the day of the presentation I was nervous all throughout the day heart was pumping loud and fast. I took one pill around an hour before the presentation. I did feel light headed the first 30 mins but it was a nice feeling. My heart kept pumping loudly, but at a very slow rate, which i guess is what this pill does. My presentation went so smoothly and i was calm and able to offer a solid explanation for 25 minutes. Everybody loved it and i was so calm and confident! The pill is magic.."
