Hi, there...guy. I'm a big believer in Metamucil and I suffer from IBS-D. It's a "regulator" for your bowels, meaning it will firm you up if you have loose stools, and help you "go" if you're constipated. Fiber is necessary for bowel health, and especially for those of us who don't have "normal" stools. It's been advertised as a laxative for years, but it is a way to get fiber into your system to regulate your bowel movements. You have many choices - powder, pill or wafer form. I myself prefer the wafers.
