Been on Benicar and Metaprolol for about 7 years. At first it was a PITA. I asked my Dr. last visit why no matter what I couldn't get my HR above 140. He raised his eyebrows and said "don't do that". My resting HR can be as low as mid 40's if I check right when I awake. One minute ago it was 54. My BP is good so I just watch how hard I exert myself and if the vision starts to white out (usually when very hot) I drink something cool and relax for a few. Sucks when it happens on a 40 foot double jump on the MX track.
