Hello, I had been on propranolol 80mg for just 4 days for stress and slight anxiety and they made me feel terrible, i felt faint and had a very slow heart rate so my doctor advised me to come off them,that was last friday. I'm still suffering from the side effects i feel terrible. i've got a very tight chest which hurts when i breathe and my throat feels like its closing in its just weird very hard to explian, my arms and legs feel tingly and i've felt faint on occasions to. I went to the doctors and i was told it was a bad reaction to propranolol im wondering if anyone has had the same problem as me or if anyone knows how long it takes to get out of your system completley. i feel awful
