high blood pressure
"I'm a 66 yrs old Caucasian male, who's suffered an increase in blood pressure from my late 50's. In reading the reviews I've realized how many side effects I've been experiencing. 
Swollen feet and ankles, Chronic tiredness, Multiple night time awakenings, Leg cramps, Significantly decreased libido.
This last effect is what grabbed my attention most severely, so I will stop taking Bystolic. "
