I have been on toprol for sometime now, and what I have found is, I have no sex drive at all which is causing problems in my marriage. I am always tired, can't remember anything short term that is and my shoulders are always hurting as if I have been lifting weights. I am also noticing bruises if any kind of pressure is applied to my skin which is weird. I also get swollen ankles and lots of hair loss. My vision is giving me lots of problems. I now wear glasses that are so thick you would think I borrowed them from the bottom of a Pepsi bottle. I just don't know what to do anymore. I have expressed most of my symptoms to my doctor, but my cries have gone unheard. I am afraid to stop taking the medication in fear of having a heat attack.. I have taken my daughter through a specialized school until she was able to manage herself but today I cannot remember how to do math or just simply write and essay which I think is weird. I am also having a hard time with spelling and reading long passages due to my lack of energy and concentration. Does anyone have advice that is helpful?
