Is anyone else taking Metropolol for heart rate? I have low normal BP, which makes it hard to take. I switched to evening but now I wake up five hours later and cannot sleep. Also I am losing my hair. I thought the Pacemaker would manage the heart rate better. It was implanted after an almost deadly prescription for Flecainide, which never should have been prescribed for someone with chronic AFib. It is contraindicated for us.
