hi, I just wanted to mention that Burroughs says the cleanse can be undertaken for 40 days and more,if necessary, and that it has all the nutrients to sustain the body during this time. I wanted to do the ten days only, but found that I was still detoxing, so I'm keeping on going. I'm at 15 days now. It's all a very individual thing. You just kind of know when it's time to stop. Some people stop way before the ten days, as well.
