high blood pressure
"Bystolic saved my lifeI had atrial fib which was out of control.  Metoprolol another beta blockers and one calcium blocker didn't get me below 100 with my atrial fib.  Plus they had horrible side effects, depression on metoprolol.  Bystolic has me at 70 pulse with no mental health side effects at all. NO anxiety or depression. I sleep better (although I nap still) .  A miracle drug.  Insurance company tried for years not to pay, saying it was for high blood pressure only and I didn't have that.  I could go back to work for god's sakes.  I'm just glad I can afford it."
