high blood pressure
"Have very frequent Premature ventricular contractions (PVCs), heart testing said my heart is fine. Put me on metoprolol succinate ER. Been taking for a year now & PVCs are still as often as they were. I see/feel no improvement. Taking at night & valsartan in a.m experiencing BP drops. My BP is very high in the morning, like 167/110, before I take my daily dosage of valsartan. Within 2 hours of taking it my BP hasn't improved, then at about 5 hours after I take my BP med my BP plummets to like 71/54, sometimes lower. I fall asleep without even realizing it when it happens & sleep for about half hour. BP readings, about 4 times daily, shows PVCs at all times with an infrequent no PVC  reading. Not convinced this med is doing anything for me."
