Day six of weaning off the Toprol. Had been taking 50mg when I was told to change medications. I took 25 mg for 4 days and since have been taking 12.5 mg daily. Chest tightness is excruciating at times, shortness of breath off and on (more ON than off) - headache, and tons of anxiety, barely sleeping because chest tightness makes breathing difficult. And all this with taking 80 mg of Diovan to help keep the rebound effects down. This is such a HORRIBLE experience. I hate it. Wonder when I will start to feel better.......
