high blood pressure
"I am a 45 yr female who developed high blood pressure 160/100. I took Lopressor for 3 months and hated it.  I am a pretty fit and active person and on Lopressor I became so sluggish and tired I couldn't function at all.  My doctor gave me Bystolic one month ago and I love it!  I feel like myself again.  No side effects at all. My heart rate stays normal all day!  Anyone feeling really bad on medicine they are taking should ask doctor to try this medicine. "
