I have not had an IBS attack now in ten years, I changed my diet completely to whole grains, fruits, veggies and lean protein plus found ways of calming myself from stress. I had it so bad for a year I thought i would never get well. my doctor put me on donatol for the cramps and pain, but the diet change for me seemed to work wonders plus a change in personnel at work. I was literally stressed into cramps and the alternating constipation and diarrhea. I disliked some things that were going on at work so talked to my supervisor and some changes were made so the atmosphere became much less strained. I know that now there are several new medications that work really well so do see your doctor at once. I was put on a new med but I was so allergic to it I broke out in huge hives. good luck.
