I think over the past almost 10 years I have purchased every supplement listed on this board, used them in every combination and tried every script. I was a severe C with debilitating bloat and fatigue. Nothing got me going. Sadly (and hopefully this will change) I've found the only thing that really helps me is eating a VERY soft SFS diet. I eat almost NO IF. I know IF is supposed to help you go, but even small amounts stop me up. I can't even tolerate acacia, benefiber or most of the other sfs. I eat a lot of bread and butter (dairy doesn't bother me) and a lot of pasta and chocolate. Not very healthy, but at the moment it has taken care of most of my symptoms. I also take peppermint caps to break up the minor gas bubbles, but I think it makes me fart like mad!!! Just a thought, if nothing is working, try eliminating all fruits, veggies for a stint and see if that helps.
