Hi,
Here's an article which I read in the Independent which mentioned there had been successful trials which cured IBS by getting the patient to drink worms eggs. Unfortunately you'll have to pay a £1 to read it on line (I read the hard copy back at the start of March) but hopefully it will help you in some way.

Best of luck,
