It was similar for me. I'd get migraines a few times a year. I couldn't find any food correlation, but it seemed to often happen the day after doing strenuous activity, sweating a lot and drinking a lot of water. I started to suspect it was related to lack of electrolytes, so I began taking electrolyte solution after running or any other sweaty activity. In the few years since then, the migraines have been much less frequent, and about half as intense.
