check your daily processed food intake for MSG or FREE GLUTAMATES. Nearly all processed food contains Flavour enhancers. Even flavour enhancers like Barley Malt,Yeast Extract,Malt,can trigger Migrane Cluster Headaches. My experience with Topomax was that it increased the effect of the MSG to make the Headaches worse. A side effect of Topomax is a change in taste for some people,MSG and FREE Glutamates are Flavour Enhancers which also alter the part of the Brain relating to taste.Try just eating fresh food and Vege for a few days and see what happens,using no sauces,spices,herbs etc.it might not taste very good at first but you might be surprised at the result
