On rereading your post I believe that once you start bp meds you are on them for the rest of your life. I tried to lower bp before meds by increased exercise and it did not work. For sure talk to your doc.
From doc's point of view why would he risk your having a heart attack by taking you off bp meds? My gp says that I have a 10% chance of a heart attack in the next ten years according to my risk factors...I am sure it would be higher without bp meds.
