I am also on Beta Blockers. I would be afraid to stop taking them because of the reason I started in the first place. I have Mitral Valve Prolapse and was having alot of problems before taking b.b's. I lost 30 lbs. while taking the b.b's. I just took Dr. Atkins advice on taking things like L-Carnitine and alpha lipoic acid to help with the metabolism problem.
