@dc10 , welcome. It's such a miserable thing to deal with, and very frustrating that doctors don't seem to have many answers.
On Clear Passage, my feeling is that you should be very careful before you lay out large amounts of money for their "treatments." I have not read a shred of evidence from the legitimate medical community that what they do really works. Look carefully at the list of "authors" on any of the Clear Passage "studies" in medical journals, and you'll see that they include the people who own the company--seems sketchy to me. I figure that, if the technique REALLY worked, it would be offered by legitimate gastroenterologists all over the world to offer some relief! Just my two cents...
But if you read through these threads you should find a lot of pointers on what diets and other tips people can recommend to at least make the issue more bearable.
Feel free to ask questions!
