Geez-100mg every eight hours wasn't enough. BP is still pretty high, so now I have to take 200mg every eight hours. I asked her if it wouldn't be safer just taking me off work, and all she had to say was "oh, we're not worried about this medication". So she scheduled me for another month. I have to take my bp an hour after I take the pills. At home it's much lower than it is at work. I'll keep you posted.....
