Hi, I have started taking propranolol recently, since I have recently fount that if I have to make a presentation to more than 3 or 4 people, I become sweaty, nauseous, and feel like I could almost faint. I have taken propranolol twice (two tablets each time), and I think it has helped, but I still seem to sweat profusely for the first 10 minutes... still very embarrasing. If I take a stronger dose, will it help control the sweating? Thanks.
