Strange relief

I have been having migraine since teenage. The triggers being sunlight, cold air, spicy food, fish, less or more sleep, missing meals, any change in schedule or place or emotions. Recently I had frequent bouts due to change in place and diet. Was feeling lethargic since days. Went to a restaurant with friends and all reported diarrhea. Me too. But most surprising thing was I felt fresh and the migraines were gone!!
