I am having severe dizziness and my cardiac doctor thinks it might be my pills. My BP got done to 55/45 and so I stopped my Valsartan but Monday he told be to also stop my Coreg CR 20 too. In the mornings I get good BP about 100/70 but by bedtime it goes up to (just now) 148/84. Seems like a lot to go up over the day. Based on my Omron BP786N. I'm thinking I need to start again on something to keep it in a good range all day. All suggestions? Not doing the Coreg is helping the dizziness but the higher BP makes me nervous. It's a few months to see him again and I'm wondering if I need to go back for an adjustment sooner.
