Not to be preachy, but the whole master cleanse concept is resting your digestive system. Burroughs apparently found this great combination. If you want to alter that, your body is your temple, but to achieve his results, I'd say stick to it as it says. I try not to do any tea beyond the lax tea. Other than that, water, "lemonade", and that yummy salt water. Try it his way at least he first time. Who knows, maybe you'll find a better method, but see how it works his way first.
