I started slowly adding probiotic .. I chose Keifer, and followed FODMAP elimination diet to see which foods in general might cause cramping, etc. my good foods were white rice, fish, eggs, and cheesecake for extra calories. Gluten free bread and 1/2 banana, coconut water, broth, all worked best initially.. gradually I could add a food one at a time to see if I was ok for a few days. Also watch for diverticulitis! And H Pylori! Also, thank God for stool softeners and Gas-x! It does get better!
