, I take generic Metoprolol myself, very inexpensive too. I take 25 mg
twice a day, normal release medication. The side effects that were the most troubling to me, dizziness, passed after taking the medication for a few weeks. Maybe you need to give your medication a longer "test run". Just be careful, I don't know what your side effects are, nor am I qualified to evaluate them...just sharing my experience with BB. My condition is Atrial Fibrillation.
