I can do shrimp, crab, lobster but not fish I don't know why although I haven't tried salmon yet I hear its not as fishy taste. Watermelon does the same to me but I can do cantelope ok and bananas. Dairy don't bother me much. Just shows how everyone is different and has to figure out their own trigger foods
I hope you get to feeling better soon, let me know how you're doing
Take care always!
