I'm glad that worked for you and that you're feeling better, but
(1) for most people with IBS, dairy is a HUGE trigger food - even in something like yogurt. A much safer way for most of us to get the benefits of yogurt without the agony is to take a probiotic supplement - available in health food stores - which works just as well, if not better.
(2) This message board IS for the discussion of Heather's IBS diet, which definitely does not advocate the consumption of dairy, as it is a trigger food. On the main forums page, Heather requests people who post on here to read her diet guidelines, and stick to posts that conform to those guidelines. I really doubt your post will be deleted - I'm just saying.
Personally, that approach would NEVER work for me: dairy, even yogurt, gives me terrible diarrhea, and calcium supplements bind me up painfully. But hey, everyone's different - that's the unfortunate nature of IBS. I'm glad you're feeling better, and I hope you continue to.
