I'm not especially fond of this article, but thanks to Dr. Levy's book MAGNESIUM Healing Disease, I (and his readers) know the probable cause and apparent cure for migraines. You guessed it, magnesium. You'll note that this web article fails to mention magnesium.
I am reading via Kindle, but will go back add some quotes from the migraine section soon.
