Fiber supplements are good but start out slow...don't take full dose at first...even ppl without ibs who overdue on fiber supplements will get major gas and bloating....imagine what that would do to us lol I think citrucel is one of the better choices because the fiber that is used does not ferment in your stomach as some of the other supplements do. I am also sure that Heather's brand would also be a big help....just remember START OUT SLOWLY!! If it calls for 2T do 1t try that for one week then the following week do 1 1/2t-2t up it gradually.
