personally i believe that you must detox at the right rate. not too fast, not too slow. and only you can find that rate, no one else lives in your body. thats why you have to experiment with different dosages and find the one that works for you.
try this next time you feel like you did too much cellfood or any other supplement - eat an apple. sounds simple but it works. the fiber in the apple will absorb toxins and usher them out. the malic acid in the apple helps break down toxins also. i have done this before and found it to work very well.
