Irritable Bowel Syndrome Message Boards | Question on insoluble fiber and IBS-C

I'm IBS-C and I originally tried Heather's IBS diet a few years ago, but it only seemed to make things worse. I'm retrying it again, because nothing else I've tried since then has worked.

From reading some of the older posts on the subject of fiber and IBS-C, it sounds to me like I need to take as much insoluble fiber as I can but buffer it with even more soluble fiber to reduce the insoluble fiber's "trigger" effects. From what I understand, I need to eventually be taking *alot* more insoluble fiber than someone with IBS-D, because it is the insoluble fiber that gets the colon to move things along more quickly. I often suffer from gas and bloating, so for the soluble fiber supplements I plan to stick to products like Fibercon (calcium polycarbophil) and Citrucel (methylcellulose) and Heather's acacia. My question is, should I rely entirely on my diet to supply the insoluble fiber, or is there an insoluble fiber supplement I could take, of course well buffered by the various soluble fiber supplements I listed, that does not also cause gas and bloating?

I had started to take some psyllium with the acacia, because that has some insoluble fiber, but I am going to stop that because of the gas problem.

It seems like the majority of the info on the web site is geared mainly toward IBS-D types, but, from what I've gleaned from the message boards, the IBS-C's typical diet/supplement program needs alot more tweaking and casting about. Thanks for any advice and insight anyone can provide...
