As far as the metoprolol goes, the two indications for that drug in this situation, that I am aware of, are for heart rate and
blood pressure. If you can get off the drug without any adverse effects on your
heart rate or blood pressure, then maybe you can do without it. You're on a low dose, so it's hard to see that it could be doing all that much, anyway. I would ask the doctor for a trial off of it, to see.
