heard from a distant relative today who has ibs and has come through it all. her method was to come off foods completely for about 4 days(fluids etc only) and then gradually different foods over time until she had identified her problem foods. I dont know the ecaxt details and i heard this second hand and am yet to talk to her myself. Has anyone else heard of or tried this method? extreme i know but at the end of the day who cares if we get results?
