I have many of the same reactions to this med that I have read on this site. My sister is on this med and we began comparing symptoms, which were many of those listed here..total energy drain, dizzy, unable to concentrate or even focus, depressed. I feel like I can't get a full breath in my lungs and I find myself sighing a lot, which does get more air into my lungs. It is hard to describe but it is a very bad feeling that I am slightly dizzy, slightly nauseous all the time. No ambition, staying in bed more and more because I just feel bad most of the time.
I stayed on this med for four months trying to see if I would eventually get over these feelings. Didn't happen. This week my Dr. try changing me to Cozaar for my HBP so I am in the process of weaning myself off Metroprolol. I was only taking 25 mg 2Xday so I cut them in half and take twice a day. I can already tell a difference in my energy and general feeling of well being. Dr said after one week of half dose, to stop completely and take only the Cozaar. I hope this works. I appreciate all the input on this topic here.
