I think the MDs are concerned that if they don't put you on meds to control every damned thing that "might" happen they're not covering themselves. I was put on a med for high BP which I don't have. There were at least 4 other meds to go with it. And, it damn near killed me. I won't go into all the symptoms but I was a mess. I called my Cardiologist who said, "Why don't you stop taking one at a time to see which one is the problem." I said, "How about if I stop taking all of them until I get back to normal?" And, that's what I did. Later when I was off everything but the aspirin my Cardiologist switched me to Crestor instead of Lipitor. Haven't had a problem since. In fact, when I took a stress test I was in great shape. Now when I get on a tread mill and bring my HR up to 90% max and then drop down to a walk my HR drops 30 beats in a minute's time. Really good recovery I'm told.
