U have cured my IBS (as has my brother, who had identical, severe symptoms for years) by taking a heaping tablespoon of raw flaxseed everyday w/ a glass of water. Cheap at any good healthfood store. When I stopped, as an experiment, it returned.Take it any time of day or nite, within a roughly 24 hour period. Works for us. Ho[pe it does for you too. May take a few days to kick in.
