I don't understand the need for colonics or enemas. It is a fallacy that toxins get reabsorbed, if that is the reason.
If i have a juice it makes me want to go, so don't see the need for them or the SWF (Salt-Water-Flush) to get bowels moving. Does it really matter if you don't have a bowel movemnent during the fast anyway, especially if it is fairly short fast anyway. I would use SWF (Salt-Water-Flush) as and when needed not as part of my routine anyway.
