I was on 50 mg of Metropolol for 4 years for HBP. While on it I gained 50 pounds, could not lose weight, although I would eat less, developed anxiety, depression, loss libido, was irritable etc. My husband could not figure out what was wrong with me. Before taking it, I was always a happy go lucky person without mood problems. I also developed palpitations while on it. I have recently weaned off due to cardiologist putting me on a Triamterence, a diurectic and have lost 18 pounds. But watch out, I weaned myself off from 50mg to 25mg and then to 12 mg in a period of 30 days and have now experienced extreme anxiety, fear of losing control (panic attacks) and shaking at nighttime. Has anyone experienced these withdrawal effects even after tapering off so slowly?
