Hi gal, I myself suffer from migraine for many years, doctors told me there's no cure. But recently I was told by my Yoga teacher that a breathing technique (a practice) can cure migraine, it's called Kapalabhati.

And since I started Yoga, the occurance of migraine on me has cut down.

Hope that helps.
