Was taking 50mg metroprolol tartate (1) nightly, cut it in 1/2 now. Side effects are Always tired, swelling of feet/legs (maybe other areas),shortness of breath upon light exercise, weight gain. Blood pressure is fine. Is there anyone else out there with the same side effects ? Anyone had these and switched to different med. with better results ? Really tired of the side effects. Has anyone quit this cold turkey with positive results ? No insurance right now, so no doctor soon.
