45 y/o female, nurse, prescribed Toprol XL 50mg daily. Could not take drug at bedtime as suggested by MD. Was not able to sleep. After a few months experienced visual problems, joint and muscle pain, anxiety, gi upset, weight gain as well as sleeplessness and heavy sensation of chest along with shortness of breath. Complained to MD to no avail. Called cardiologist, he suggested brand use as opposed to generic. Apparently, generic drug does not provide continuous steady release. Also, he lowered dose to 25mg daily. Will report subsequent effects but hope to be weaned off the drug entirely. I appreciate all the information that has been posted on this site, especially the beta blocker info. Hope this helps somebody else!
