I am starting Colestid today for my "ibs" which probably isn't ibs but stupid doctors who fail to investigate thorougly label it that. If you have had "IBS" since your colestectomy(gall bladder removal) you may have bile salt disorder and Colestid could turn you back into a new person. It helps bind the bile which is making you run to the bathroom. It's worth a try, and I will be reporting on this medicine to say how it works. I started tonight and will give it a few days to truely see.
