While doing The Master Cleanse
people do the salt water flush every morning, some for up to 40 days. I don't see where it can hurt you but you should keep up your fiber so that the bowels can still work on their own. You don't want to become dependent. I don't know how it can unbalance you as nothing is absorbed in the system with the flush, it just goes right on through and cleans you out. Hope this helps you.
