@howard137 I can sympathize. I went to my cardiologist for a regular visit about a year after he had prescribed metoprolol and told him I thought it was stunting my physical output. He said no, it's not the metoprolol. Bull pucky, dude. To his credit, though, he did say he wanted my to keep plugging away at physical fitness because that much of my existence was going to keep my heart in good form if not in great rhythm.
