Benay, to add another list of suggestions for IBS-D, read Dr William Davis's new Super Gut book. I just got my copy from the library and there is a LOT to wade through, plus I don’t have IBS so have not been good about retaining all his suggestions, skimming the detailed instructions.

But after reducing the "bad" microbes, much of his new protocol involves making your own yogurt with specific strains of bacteria, eating certain fibrous and fermented foods, adding some processed fibers…there are many steps! though he is always giving alternatives to make it "easy" and more practical. He has some new versions of his yogurt recipes to try as well.

I believe Jean, cotonpal, is a member of his Undoctored group has made the yogurt ?? And maybe WearBear has the book??
