I second most of what Jeff said. It doesn't have a flavor, and just thickens whatever it is mixed with.
The only time I have used it is by doctor recommendation for prep before a colonoscopy, and yes - it worked very well, but that was probably a bigger dose than on the label.
As for the risk of obstruction, that sounds like you'd be using it on a daily basis, adn that doesn't sound like a good idea to me.
