Hi, Susan! Good luck with your search. Keeping a record of anything negative is a hard chore. You just have to have the attitude of "I'll get you, you little migraine demons!" I'm an older guy, so I like to keep records like that on paper. If I attempt that electronically, either I'll accidentally delete it or send it to an archive, meaning "God only knows where it went & he's not telling!" But, my paper search was successful! While my primary trigger is weather changes, my food triggers turned out to be coconut oil & palm oil. That info turned me into a voracious label reader at the grocery store. So, if I can do it, you can do it even better! And if you would, please keep us posted. We care!
