Give the Acacia a shot - start at a low dose and increase gradually.
Have you tried the IBS self-hypnosis program? That is a "last resort" option that should really be used as a first resort - it has helped people who have felt that they had no hope left. There's a ton of info on the site about it - just click the "Hypnosis for IBS" link to the left of your page.
Please let us know how things go...
