I take Metoprolol ER Succinate 100mg tab twice a day for essential tremors and have for several years now. I am looking at finding an alternative substitute since I am having several side effects from it such as Dizziness, Tiredness, Dry mouth, gas, heartburn, and cold hands & feet. I have a history of bi-polar depression, acid reflux, high cholesterol, tremors, and IBS. I take several medications for all of them. Lately I have experienced severe fatigue and high blood pressure (160/100 and tonight 145/96). Any alternative substitute for the Motoprolol is appreciated. Thanks. David
