high blood pressure
"40 y/o, white female, moderately active.  So far I'm happy with this medicine.  Bystolic brought my blood pressure down from 200/110 to 124/74 and my heart rate from 120 to 48 on 10 mg (and 1mg of Guanfacine). I have gained about 4 or 5 lbs. during the 2 months I've been on it, but I can honestly say some of that is my own fault.  I, too, have experienced a calming effect.  Aside from the gained lbs. I have no complaints."
