Comparing Metoprolol vs Metoprolol Succinate ER

For High Blood Pressure I have taken Metroprolol (Beta Blocker) for years for high blood pressure caused by renal FMD. The negative side effect was primarily on cognitive function plus cold hands and feet. My short term memory really became poor. i experimented by taking myself off it for a few weeks and then putting myself back on it. I was able to measure a clear difference in cognitive function. I decided to refuse to take any more Metroprolol and my doctor found me Felodipine which is fine.

For High Blood Pressure I run regularly and have a resting heart rate in the low 50's. I'm 56 years old and have been on metoprolol for about 3 years until last week. I also recently gave up caffeine. Last week I was sitting with a client and fainted. After a trip to the ER and an overnight hospital stay, I learned it may not be a good idea for anyone who runs regularly with a low resting heart rate to take a beta blocker. It could've have been a much more expensive lesson 20 minutes earlier while I was driving. Now I am searching for the best BP medicine for runners.. Any suggestion would be appreciated.

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.
