I follow the Auto Immune Protocol due to my Hashimoto Thyroiditis and Ehlers-Danlos Syndrome. I have not noticed a difference, but I do avoid chewy and crunchy foods like chips and gum, taffy, jerky, breads, etc as I believe food texture impacts my clusters more.
I never drink cold drinks. Always let everything warm up to room temperature. Once I accidentally get a brain freeze, I feel like that nerve stays irritated and triggers clusters easier.
