high blood pressure
"I have been on metoprolol er 12.5mg since September 20th. The first month was great then on October 21st my resting heart rate went from 61 to 70 and when I walk it suddenly goes to 140 for no reason. I work out 6 days a week and it doesn't make any sence to me. Going back to my doctor tomorrow to figure it out. I just don't see why all of a sudden it would make things 10x worse. I didn't take it today to see if it would help. I was able to exersice without my heart rate sky rocketing to ridiculous numbers. This is the first medication like this I have ever taken. Plus the weight gain is ridiculous. I lost 15 lbs before starting this medication and less then 2 months I gained it all back."
