I'd ask about something else. That is a beta blocker (blood pressure pill). I was on it and of course it lowers your blood pressure and knocks you out and makes you feel weak. It takes a while to get used to and if you took it one day you'd have trouble concentrating and focusing at the presentation because of the side effects. That's not to say its unsafe or not worth using but it takes to accustom yourself to it. And speak to your psychiatrist not your doctor. Your doctor would know of its usage for blood pressure and other physical usages but your psychiatrist would know how to titrate it for anxiety. And he probably could think of something with less side effects.
