My parents first thought it was an allergic reaction to walnuts, since I was having more frequent attacks
and it was the holiday season,
and I was eating dozens of
walnuts a day. So I stopped eating walnuts. I was convinced though, it had nothing to do with walnuts. So one day I managed to sneak a few walnuts out of the kitchen. Nothing happened. I didn't again- same result. Today, I eat walnuts freely, and have no attacks. It's NOT a food allergy.
