I am in the same boat. Dont be afraid to keep trying. I am doing The Master Cleanse primarily for weight loss and secondarily as a cleanse. I see no problem in this. I look at it like resetting myself. The key, as always, is beyond the fast. It is an opportunity to emerge with good and healthful habits. I will be feeling better because of less weight and improved health. This is the perfect platform from which to adopt healthy change.
