First, I know different people have different triggers from me. I used to have migraines every few days to every few months from age 13 to 23. These would incapacitate me. I would get the aura and be almost blind for an hour, then throw up a couple times, and have a bad headache for 2-4 hours, then I could function again but still felt crummy for the next 24 hours. I noticed that pickles were a trigger, and I thought "pickles have a lot of sodium". So, out of desperation as something to try, I read the labels of everything I was eating and cut out everything that had more than a little sodium: frozen pizza, frozen dinners, deli meats, etc. At the time I was having migraines every few days, and then I didn't have another migraine for years. I was so glad they stopped. I now doubt it was the sodium. In cutting out sodium, I happen to cut out processed foods, which includes lots of suspicious ingredients. I suspect Tyramine was the main culprit. There's a diet called The Headache Diet that is focused on minimizing Tyramine. Guess what else pickles have a lot of? For last last 30 years, here are all the things that have caused my migraines: Lithium Carbonate (Orotate is OK), Pickled Herring (Tyramine), Soy Sauce (Tyramine), Hyaluronic Acid (synthetic, Mobilee is OK), Tianeptine, Sulbutiamine, and a strobe light. Every migraine I have had in the last 30 years can be explained by those - only 8-12 migraines total. I still precisely control my sodium and eat no processed foods.
I too had nausea, auras with migraines when I was a teen. I think I outgrew them. That or it was my girlfriend at the time (I was about 20) that gave would snap my neck — like some kind of self-taught chiropractor.
