Your body is doing exactly as MH says... The old in-organic matter is being broken down and removed from the body... I have done a 21 day fast and have been a fruitarian for 9 months... I have had cramps, twitches on lower legs up until 7 months and slight pains everywhere over my body... This is GOOOD news!!! Keep up the wonderful cleansing... One of MH top teacher explains that when a body is removing old matter a ailment will reappear when you are cleansing. Such as I had heart palpitations and since went fruitarian. 9 months later I was on day 11 of my OJ fast and had INTENSE heart palpitations. I believe in OBEYING NATURE and they vanished within a day. I have not had any since!!! After 14 days you have 5x the red blood cells and even when you stop fasting the amount of blood cells times 5 remains. I have experienced a increase in my bodily cleansing as a result of surpassing 14 days.
