I do understand what you are saying. For me it is dehydration and stress and constipation. I drink lots of water and prefer to eat less, but you know stress doesn't see things that way. Stress wants FOOD. So it is a battle. I have no trouble with fiber, and I actually do much better with a high fiber diet as long as I keep drinking plenty of water. So far, I have not had to take any antibiotics. I drink lots of juices and also green tea. My DH is in the bathroom all the time with the Crohn's, but I have the opposite problem. Interesting thing, the GI dr. gives the same directions to him that he gives to me. And it's the same GI. So far we are doing pretty darn good.
