Sarah, I had a chance to read the book today (briefly, the vicious cycle one) and the author said that it's recommended for people to stay on this diet for at least a year, without changing it, before the alter it. Yet you said in your original post that your friend advised you to try incorporating new things only after two weeks. Is this because the book is mainly targeted to IBD and Crohns and we're "just" IBS?
I have to say I'm really tempted to try this diet. I kind of tried following it today for some meals but I know that I'd have to give it a full shot. I probably wouldn't stop my probiotics, however, because I feel that if bacterial imbalance is the problem then the bad bacteria should be starved off by the diet, and the good guys should be replenished.
I'm also trying to make the yogurt the book describes. Even if I decide not to eat it my hubby will so no loss there (unless it doesn't turn out good ). The diet just sounds so encouraging that I think tomorrow I'll try to follow it properly. I do have a few social things in the next couple days (dinners, relatives) but even if I don't manage to stick to it at least I will get my feet wet and start again. Two weeks is not too bad, I'm just a little afraid that I'd have to do it longer before I see results and start incorporating new foods. But I'll play it by ear! How are you doing?
