high blood pressure
"After a few decades of high blood pressure, my new doctor switched me to Bystolic.  2 days later, I was within normal range for the first time.  I absolutely love the results of this med.  I have had very vivid dreams, insomnia, and tiredness during the day.  I was willing to deal with that.  Here's the problem...I started with a "coupon" which was to make my maximum monthly cost $30.  I filled the prescription in April, and it cost $30, but in May, it was $65.  The pharmacy was told that the coupon "changed" May 1.  I called the coupon administration office, and was told the same thing.  However, the coupon says right on the back that it is valid until December 31.  I feel I was deceived! I have asked my doc to switch me to something else."
