Re: BP meds. There are two types. One will dilate your blood vessels (vasodilators) and the other acts as a governor on your heart (Beta Blockers). At least that's the way I understand it. Beet juice, although not a med, acts as a vasodilator. I was on Coreg which is a beta blocker. So, my heart could not beat past a certain point. I don't have to tell you what happened on group rides when we hit a climb. In addition, I was always tired and depressed. I'd get up at 6 AM and have to go back to bed by noon every day. It was miserable.
