I have had a lot of reflux since starting the gluten challenge. My GI gave me some meds to take to hopefully help a little while on the gluten challenge

Imodium and Pepto Bismol are relatively safe when used occasionally. Pepto Bismol will bind with medications. I cannot take it because it will interact with my coumadin. Pepto also contains aspirin in it so it can make platelets more slippery and the aspirin could also cause ulcers if Pepto is used too often. I'm not saying the restaurant meal is the ongoing cause of your diarrhea episodes. I think more likely gluten is slipping into your diet on a regular basis somehow or you have developed an additional food intolerance. Have you investigated the possible causes of high eosinophil counts? One of them is autoimmune disorders and of course, celiac disease fits into that category.

Thank you for the feedback!  I realize the restaurant meal was probably contaminated but I had no idea a reaction to gluten could last so long!  I’m hoping I find a doctor who will take me seriously.   Is Imodium or Pepto Bismol safe to take to manage symptoms?  

Welcome to the forum, @Julianne101! Your experience is exceedingly common in the celiac community. First, regardless of how gluten free the food was in the restaurant experience you described actually started out to be, you have no idea what measures were taken in the cooking, preparation and handling to prevent cross contamination. Sounds like to me you are either getting gluten from some unexpected source or you have developed additional food intolerances. It is very common in the celiac community to be intolerant to dairy (CMP or Cow's Milk Protein) or to oats (even gluten free oats, the protein avenin) which have proteins similar in structure to gluten and can be cross reactors.
