Hmmmm I can only say that the last year I almost ended drinking my piss out of desperation. Went only as far as to do URINE ENEMAS. Didn´t feel much, except some marginal disgust.
Some people claim it is a panacea. It just looks like some atavic pseudo-profilaxis to me. I envision hairy yogis drinking urine in the dessert to attain enlightment, back then in the dawn of civilization.
I have also waterfasted for 14 days straight and I STRONGLY recommend you to avoid it.
The advice on CureZone has led me to feeling worse most of the time ( Liver Flushing and coffee enemas come to mind). Most of the people in the AF forum aren´t delusional freaks fortunately.
