Comparing Metoprolol Succinate ER

For High Blood Pressure: I originally started taking Metoprolol 25 mg once a day due to SVTs. they helped calm them down a bit. I also have PVCs and PACs especially when my blood pressure is superhigh. I am now back on this medication and started at 25 mg, within a few months it was up to 50 mg, I recently went up 100mg from my GP, but now my cardiologist up me to 200 mg. I have been only taking 100-150 mg. I break to be 100 mg pill in half and take 50 mg every six hours. My blood pressure went from 197/130 to approx 147/97. I have recently changed my diet dramatically and Inc. swimming and walking as an exercise. 49F, 208lbs. Sedentary life for 5 years. No side effects at all. Take with food though as directed. Causes nausea w/o food for me.

For 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.
