@luckyhowreyou @bbisno @danafitz I wish to add one more thing to this helpful discussion on Metoprolol side effects - dizziness - vertigo - fatigue and the rest of it. Hydration. Are each of you well hydrated? I find that if I am not well hydrated, I get that dizzy-not-feel-like-myself. I am always asked by my cardiologist and PCP how much I drink each day, both recommend 2 liters/quarts each day for me. I have a 32 oz refillable water bottle that I fill twice a day. Both HCM and Metoprolol have a negative effect on kidneys; water keeps them well flushed. Hearts and related matters function better when hydrated. We get more liquid from food (think juicy apples and oranges) that adds to the 60+ ounces. Ask your doctors how much water you need to drink every day.
