@bentley33 , you sound so much like me, except that my episodes are acute (short and very severe) as opposed to chronic. Either way, it sucks!
I've said this several times here, but I'll repeat it--think very carefully before you spend large sums of money on Clear Passage. I have seen ZERO credible evidence that it helps (if I thought it did I would do it in a heartbeat!).
Any "studies" I've found in medical "journals" have been co-authored by the owners of Clear Passage--not exactly objective! And I assume that real GI doctors would be recommending it (and insurance would probably cover it) if it really worked.
Perhaps I'm wrong, but the whole thing seems like a money-making venture that tries to prey on desperate people like us. And they've made sure that they pop up first on almost any kind of internet search regarding obstructions!
