Verapamil
"I have suffered for three years, at my whits end I too did my own research and after two weeks I am pain free.  The bad attacks stopped instantly and the minor ones subsided after about day 7.  I feel like I have my life back.  I was exhausted for the first week until my body adjusted...but push through people....this medicine saved my life.  I can even enjoy a glass of wine now and again!"
