high blood pressure
"I have taken several beta blockers over the years and they all have various side effects.  I recently switched to Bystolic and my experience has been wonderful.  I have not experienced any negative side effects.  I have more energy, my heartbeat is steady. I have also been able to exercise without getting tired, which has helped me to lose weight.  This medicine also seems to be working well with the thyroid medicine I take. It is a little more expensive but well worth the cost."
