Even though I only prepared for about a month, obviously my body did not go into serious detox until about day 33 and even then it was mainly nasty taste in my mouth and nausea as a result. This is very individual and you cannot use cookie cutter here. You are making general statements. It all depend on the organism and how it functions. Someone who has pathologies or disorders will have a different experience then someone like me. Ultimately it is about educating a person of all the warning signs and making sure that the blood work and the physical was done prior to the major fast.
