I tried it, and it was ok. I only bought the sampler bag, which isn't very big, and you use 3 scoops of it per dose, which I thought was a bit much so I cut it down to 2. It tastes a little funny, but it seems to do the trick. I don't think I used it enough or for long enough to credit my progress to it, but it's always worth a try! Get the little bag and see if you like it.
