Right now I'm taking 5mg on Bisopronol every morning because I have a fast heart rate. I am hoping that with exercise I can bring my heart rate down and will be able to stop the beta blockers in the future. I have read that beta blockers are really hard to come off of as they make your heart go wild when stopping them and that terrifies me. I am already scared of my own heart rate now (resting 90) it absolutely terrified me. Before taking the beta blockers my heart rate was 120 all day - nothing medically wrong so no idea why it was so high :(
