Purpose..No purpose...have just read a bit about dry fasting and how it is 3 times more effective than water...read that some people have gone 7 days dry fasting!??
OK....
Well, I did it for 32 hours on day 10 of my juice fast. I was just playing...
Not doing it again...
Not interested really.
It was draining to just sit there with a NASTY tongue and dry throat...
