I can relate to your dizziness with metoprolol. When I was initially diagnosed, that was the prescription I was given and the cardiologist kept adjusting down the dose, but I couldn't tolerate it. I was switched to the verapamil 120mg extended release twice a day. I have been on it almost 20 yrs now. I had my septal myectomy one and a half years ago at Mayo, Rochester. They kept me on the verapamil, and added the metoprolol post surgery, but after 3 months I was able to discontinue it. I have great energy and exercise tolerance now, so you might find the verapamil much easier to tolerate, as I did. Best of luck.
