blood pressure question

okay, at diagnosis my BP was normal.

then 3 months later it was high, averaging 145/95. I was put on 10 of quinipril.

3 months later I started falling down when I stood up.

went to doctor BP was low and dropping to 90/60 upon standing.

dr cut the quinipril in half.

presently, another 3 months later. my BP is around 130/over 85
thats too high, I monitor it myslef now and its usually around this range.

what does this mean and what should I do? do I have to go back to the docotr.

my resting pulse is usually between 80-90. is that okay. fluctuates quite a bit.
