I've suffered from chronic intense headaches and migraines for 50 years. Have felt cheated at not enjoying life's joys for so long! I've wasted thousands of dollars on pain relief pills for zero to quick and short or temporary relief. I received my patch 3 days ago. The first 2 days it started easing the pain from 50 to 80% with a mild nagging, lingering pain. Today, is my 3rd day wearing my patch non-stop since day one and I have no head pain! I will never be without my patch plus a few extras to be on the safe side. I thank you so much and, especially, my friends, who urged me to call you. May God bless you...
