    I have been taking “Super Cleanse” for almost a month. Results have been excellent, except the bottle says to achieve 2-3 “good” bowel movements. I only have one as I am very constipated usually. Is this a problem.
    Also, more importantly, is there a chance my body will become dependent on this supplement if I continue to take it past a month. thanks!
