high blood pressure
"I am 35 years old and my blood pressure which was an average of 150/90 was giving me headaches. My doctor prescribed me 5mg of Bystolic daily and my blood pressure dropped to 120/80 - perfect. Some side effects though. I experienced initial tiredness which waned and decreased sex drive. I haven't gained any weight but it really seems hard to lose any which I've been trying to do for a while. I think this is due in part because it's hard to keep your heart rate elevated when exercising. Overall a good drug - gets the job done."
