I think the best place to take the course migraine 101 is through a book called Heal Your Headache by David Buchholz, M.D. you can get it through Amazon.com

Not only does it do a good job explaining the dynamics of a migraine in layman’s terms, but it also does a very good job helping you learn what you can do to help yourself in terms of lifestyle and the famous migraine diet.
I highly recommend getting your hands on a copy of this book, it was the start of my education into this MAV mystery monster.

P.S. Regarding your symptoms, i was certainly fuzzy, pretty much all the time, and I suffered from flashing lights, mostly at night, but i had a lot of other confirming symtoms, making MAV a no-brainer. What other symptoms do you have?
