I am also taking beta blockers and would be afraid to stop because of the problems I was having before I started taking them. I have Mitral Valve Prolapse and have alot of problems with it. That's where the b.b's come in. I lost 30 lbs. in 6 months while taking the b.b's. I just took Dr Atkins advice about taking L-Carnitine and Alpha Lipoic Acid to help with the slow metabolism.
