I tell the doc that the med is fine, because, I know the next step would be trying a different one. And that whole process has proved to be a pain. I'd like to go off all of them. Metroprolol is like driving a car with one foot on the excelerator and one on the brake. After raking leaves, the brake wins and I sit down winded. With less of the med, I can go on alot longer, but eventually feel a bit odd and get the swelling in my abdomen. I just hang in there.
