Suggest Remedy For Abdominal Pain Due To IBS And Gluten Intolerance

I am gluten intolerant, I have also been diagnosed with IBS and have had consistent episodes with Diverticulitis. My cravings for plain milk chocolate and peppermint have been almost daily lately and mostly in the morning. When I eat the two cravings my stomach pains are lowered. I am concerned my body is lacking something more important and I would like to replace it with another more healthy substance than a craving such as a Hershey bar or York patty. Any ideas?
