Hi Casey, I've had CD for many years also located in my colon. If I have smaller meals throughout the day, I feel better. Nausea is big problem for me, and if I over eat I really suffer. I stay away from raw veggies, spicy foods, all type of nuts and pork (which I can't digest for some reason).
I just started eating less gluten which seems to help. Plenty of soups, soft foods and fruit smoothies in my blender.
I was taking Lialda for years but just switched to Asacol 4 x a day. Be well!
