Yeah I've did the odd melon cleanse but to be honest there doesn't seem to be a kidney cleanse that does a great deal or requires alot of preparation. It's recommended by some but not by others.
The possible claim that flushing creates stones is potential straw to break the camel's back. It's just pure speculation. If someone like Andreas Moritz actually said that I would definately know it was fabrication. Luckily he just sticks to the emotions not letting the body release stones, or some nonsense like that.
In any case, I'm not really here to discuss my own personal case, just the existence of stones. Thanks for your concern anyway.
