Lisa Marie, I'm interested in how you became stable as an IBS-C (and almost vegan!) And did I read that you can't eat wheat?
I'm also IBS-C and I'm really struggling. I go back and forth as to whether I need a high-fiber diet (per my GI doc) or a low residue diet (per my colo-rectal doc). Either one gives me relief in the short term (a few days) but causes problems in the long term. And I strongly suspect I have a problem with wheat/gluten.
