When do attacks occur? Well I can usually tell when I will have an attack (d)always..My stomach starts to grumble and then the cramping starts. ugh!!!But since I found this site I have been following the diet plan faithfully. Well today was D day again. I had some spinach and mushrooms with olive oil and garlic last night was a small pieces of chichen breast. I was fine...but this morning at work after eating my soy yogurt, I got sick again...so back to rice cereal (baby cereal) and plain bagel...I am here again...In my case I think it has something to do with age. I always had a sensitive stomach but as I have gotten older it has gotten a lot more sensitive..anyway that's how my day went. so attacks can occur anytime, anyplace. Thanks for letting me share.
