I am taking the Metoprolol generic and have mixed reviews, although I don't think that any of my side effects are life treating. My greatest complaint is insomnia. Most nights I get 4-5 hours of sleep. I also have the itching(hives), and sometimes numbness in my arms. I do feel much better since starting on this med in May, and my blood pressure is normal after being sky high. I can live with the hives, the insomnia is irritating, and my menstrual cycle was horrid before, and is now worse, 8 days out of every 27. Hopefully menopause is coming soon. I am taking 1 25mg tablet twice daily. My BP was out of control before starting any meds, so I will live with the side effects. I haven't noticed any weight gain, actually lost 14 pounds since starting it, but that could be the results of a low fat, low cholesterol diet too.
