Metoprolol
"I have been taking 50mg of metoprolol XL for about a yr. for hypertension ... while it has helped lower my B/P, I have side effects ... issues like hoarseness for no apparent reason, occasional fatigue  & occasional dizziness ... at times lowers my heart rate that I feel dizzy like passing out (especially in mornings) I will talk to my pcp see if can switch / experiment with another med.  In my opinion, all B/P meds have side effects"
