I did take psyllium years ago when I was dealing with IBS (or what we thought was IBS). It did seem to work though, quite well. Now that you mention it, I might pick some up and see how it does with my system now. Pretty inexpensive pills too, 10 dollars a bottle from what I remember from GNC. If I remember to pick them up, I'll let you know the outcome (if I remember to do that as well).
