I had two rounds of major migranes. Roughly three years apart. I wouldn't wish that experience on anyone. Imetrex (sp?) would kill them, I eventually learned after eating handfulls of ibuprofen & anicins. I thought my life was over the first round, and sure it was the second round I was about 40. Following a full round of diagnostics on the neurology floor in Pittsburgh (spinal tap....) I self correlated the two episodes to purchasing Large blocks of imported "Super Sharp Cheese". I quit eating it & no more headaches. Difficult correlation because no immediate cause & effect, I just thought through the time periods (floaters in the eye, massive headaches, chewing ice, eating super sharp cheese..... huh, cheese =MSG! I think I elevated my msg levels ultra high to a threshold point where a beer could kill me. No more cheese experimentation for this dude.
