Because I have done that (eat according to the guidelines in the book) and my IBS is now stable - I don't post that often anymore. However - I love the recipes - and I try an check the boards and offer advice when I feel I can. I also hadn't been feeling well in some other areas -- and that limits my computer time... Turns out I have fibromyalgia -- which explains a lot! But now I am off on a tangent. Truth is -- Heather's advice has given my life back to me. I can eat without worry. Great guidelines --- and I can't imagine how I lived before (constantly in the bathroom is how it was).
