I have none this cleanse several times with no ill effects and am currently on it...day 6. I do not stay on the maintenance program which would probably eliminate any possible addiction, but do the cleanse a couple of times per year or whenever I feel I need it. My husband, father, children and friends have also done this cleanse with no addiction problems or ill effects. You might want to add garlic, pumpkin seed and Co- Enzyme Q-10 to increase it's effectiveness. Do your research. Do what feels comfortable and feels safe for you.
