Most of us Migraineurs have an understanding, whether obvious or innate, that any potential food triggers affect each of us in different ways at different times. That being said, I've often looked to this website when I've had an impossible-to-explain Migraine attack. Once in a while, I'll see a common food or drink listed on the site, one that is a trigger for many Migraineurs, and realize I've consumed it in the last 72 hours after never having had it before (or never having had it in such quantity).
Perhaps it will be of use to you, too.
I sincerely hope the last few hours of 2007 treat you all well.
