I've used his bowel formulas and they didn't do anything for me either. The IF #1 was way too strong for me and the #2 didn't seem to do anything. I've seen a few folks post that they liked his formulas, but they didn't work for me. Try the Colonix. I'm still using the fiber and senna tea ( can't use their Paranil capsules, because I don't tolerate parasite herbs ).
