I am 45 years old and am taking Toprol because I have a severe cardiac arrhythmia. I am comforted to read this website because I see that my side effects are fairly common. I too feel lethargic, apathetic, and "heavy" all the time. There is an emotional disconnection that is disturbing. I feel kind of achy and elderly. I have had some memory problems over the last few years (they appear to have increased together with my arrhythmia) but they are much worse since I started medication. I am also bloated and can't seem to lose weight. It is a relief to know that these are typical symptoms, but I am afraid to discontinue the medication. Thanks to all of you for sharing.
