for Bowel Cleanse i take the P&B shakes as they describe at the bottom of the page.
yes fasting of course will help with the skin problems as well, and i thought of that too. but for instance my skin is now more clear than ever yet i haven't done a cleanse for over a week, and my diet is the same. i will say i do maintain a very strict diet right now, but even before with the same diet my skin always looked bad. i'm just keeping my eating really clean to speed up progress and take any stress off my body that i can. my liver is doing something now, before it could never get caught up.
that stomach pain may be related to your intestines, or sometimes they'll recommend that you do another flush if you have a reaction like that. i would ask shelley or curezone team about that one.
