I do like to take a hefty dose of a sugar-free metamucil-type product on a fairly regular basis (couple times a week). Not because I get constipated, I just think it does the entire intestinal system some good to "sweep it out" now and then.

I don't take a supplement if I am drinking the fiber, I figure it is a waste because the fiber binds everything up and rushes it through the system, thereby interfering with absorption.

I do get quite a bit of fiber from my veggies, and I'm not sure you absolutely have to have a supplement. But it is easier to drink this stuff, than try and eat extra servings of veggies.

Interesting about the sorbitol in prunes, I had never heard that! Kind of the same reaction as what I had when I ate a whole box of Russell Stovers SF candy. Whoa.
