This story begins in 1974. I tell it to you so that you will know how I came to the knowledge I am about to share with you. It also demonstrates how any person can transform his or her life from ill health and craziness to well-being and sanity. Two years out of college, I was an itinerant photographer working for whichever publication would pay me to take pictures. I ate what I wanted, smoked cigarettes, partied. And I got headaches: searing, debilitating migraine headaches.
