Welcome to HealingWell, I hope you'll be able to get some help here, even if it's just by talking. I'm glad to hear that you're trying to eliminate some known migraine trigger foods. I would probably suggest to you that you try waiting longer than a week as it can take the body a while to get used to change. Also, you may want to eliminate more than just one thing, such as chocolate, at a time. Instead, try eliminating everything with caffiene in it. And instead of just eliminating cheese, try eliminating all aged foods and drinks. That way you'll be eliminating a group of triggers, not just individual things in a group.
