I had mine out 2 years ago..... and there are still foods that affect me!!
Mostly fatty foods, but also poultry and soups with a lot of broth. Eventually you will figure out which foods are "absolutely nots" and some that are.... "occasionally but not too far away from home".
I know this may not be much help........ but I do know that with time it has gotten better and I know what to eat now with no probs.
