Anybody have any experience using this stuff? I was thinking about getting some of this and adding it into a couple of my meals for some added diet roughage. I tried some at my brothers house, and the stuff is pretty much taste less and when you add it to water you really can't even tell it's there. No grit or nothing, which makes me feel like I'm taking in nothing. Just wanted to get some of the opinions on the board before I go and spend 8 bucks for 30 Tsp.
