IBS - yeah, doesn't bother me talking about it, just wasn't sure if it was ok with you. Anyway, sounds like you and I are pretty much alike. Animal fat's a bugger. My biggest saving grace was taking a glass of metamucil immediately before I eat dinner (then later 5 capsules and big glass of water). Almost always saved me from the terrible cramping and subsequent, well, you know... Anyway, after several years of doing that, eating more fiber, fruit, veg, etc, and really decreasing my stress levels (divorce) - I think I've almost got it beat. I rarely get any symptoms now and when I do, I always know what has caused it...
