If there's anything we know about migraines, as with any malady, it's that what works for one person doesn't necessarily work for the other. There is no such thing as a panacea. If any practitioner claims a 100% success rate it's probably time to move on and find another.
One thing that worked consistently for me was EFT (Emotional Freedom Techniques). I had classic migraine (30% of sufferers) which means I had an intense visual aura preceding all headaches. It means I had a warning with about 40 minutes to decide exactly what I was going to do.
Enter EFT or tapping. OK, so it's not going to work for everybody but, it might just work for you. It sure did for me. The thing to keep in mind is that it has to be started as soon as you recognize the aura coming on.
As I said previously if I started the process at the onset of the aura I could completely avert the headache. I still had the postdrome (final phase of a migraine) but that I could live with.
Please watch the YouTube video. Educate yourself. This video is the intro to EFT and though it doesn't really teach you how to do it, it's a nice production and a good intro to the process. I encourage you all to learn this amazing technique to see where it can take you. It can mean the difference between headache or no headache and it can be a wonderful stopgap while working on finding what's right for you.
