Weaning off Toprol XL

Hi, I am currently on 25mg Toprol XL 1x day. It has controlled my hr/bp. I had all the tests and my heart is ok with no coronary artery disease. I had a series of panic attacks that resulted in me thinking I had a heart so I was admitted into the hospital. I believe the cardiologist put me on it because he knows it also can control symptoms if you get anxious. I also take klonopin for anxiety (.05mg) as well and use it for sleep and as needed for anxiety.  Has anyone successfully weaned themselves off Toprol and used non prescription ways of controlling the condition. Thanks, Mark
