I have taken 80mgs at a time for some presentations, and had no physiological symptoms of anxiety. It was freaking amazing! I was hella thirsty (chew some gum) and super tired after though. But for one presentation, the meds made it so I was able to address a lecture hall full of undergrads, explain my research to them, gather consent, and conduct some research on them, and thank them. Audience of about 120, super bright lights on me (ugh the worst) and normally I would have died from super horrible blushing, high heart rate and stumbling over my words etc if I hadn't taken it. Yes, I practiced the hell out of what I had to say, completely scripted it, but it helped so much. HTH.
