first of all i suggest that you drop all semi-prepared or prepared foods.
buy raw and cook it yourself.
on the other hand, the first improvement i saw when starting this diet was not the lack of pain, but the quicker recovery from it. as you know most of the pain builds at night, and mornings are the worst for us. well, for me there was no big difference at that time since there were layers and layers of pain. fist signs for me were the easier recovery from the night pains - i was able to do more, to move more and to rest less during the day. it took weeks though to feel this.
another thing that kept me going was the improvement of my bowel problems - i suffer from IBD, a far worse condition than IBS, but some manifestations are alike. no more gas, no more bloating, less gut pain.
