I am trying yet another preventative (verapamil), and I am told that I am scraping the bottom of the barrel. Even the Botox that they told me had a 80-90% success rate, didn't work. I am taking up to 18 Relpax a month, which they say is too many. Has anybody had luck w/verapamil (they told me that it only has about
a 10-20% success rate)?
