Hello Minded - Kiki Lou is absolutley right - eating Raw Veggies is about the worst thing you can do if you have IBS - Some suggestions that may help - go back to eating the cooked foods AND go to your local health food store and get a gallon of Aloe Vera Gel (not the juice).
You can drink it by itself or mix it with juice and it dosent taste bad, but it SOOTHES the digestive tract tremendously. You may need to take it a while. I have also heard that the herb Slippery Elm is helpful.
