I have been a severe headache sufferer since elementary school and started getting migraines in junior high. I have often suspected a dietary link, but now am positive. I have not has a single migraine since I started LC. While I have had a few normal headaches in that time, all but one were minor and responded real well to a single dose of ibuprofen. The exception was on a day that I only ate one small meal and let myself become dehydrated and went away very shortly after having a good breakfast the next morning.
