I was wondering if anyone out there is on a beta blocker. I have been on one since my pacemaker for SSS was implanted in 2004. I was wondering if anyone else was having problems with their weight because of the beta blocker. Also I have talked to other people who are on a beta blocker and they have been placed on a diurectic as well. But my doctor hasn't done that. I exercise, watch what I eat and I can't lose the weight.
