title: I take three different blood pressure medications-six pills total-every day. They are isosorbide mononitrate, amlodipine, and atenolol. They seem to do a good job bringing down my blood pressure, but before my 6 p.m. atenolol and then later before my 10 p.m. amlodipine, my blood pressure shoots up. I'm worried about carrying an elevated blood pressure for much of the evening. I know ift goes up in the early hours before I wake up, too. What can you tell me about how these fluctuations are affecting my health? My doctor says I shouldn't worry. And is it possible to keep the blood pressure under control 24 hours a day?
