I take half a pill of the lowest dose available, it also helps reduce my tremors.I had the same thing happen at my Dental cleaning a couple of weeks ago. I got a big lecture on BP being too high there. I told him that I was diagnosed with white coat high BP. He finally gave it up.
I was on blood pressure medicine but stopped when I passed out one morning because it was too low.
Mine is usually in the 120 to 130 over 80 range at home. I monitor it and am not worried either.
