It felt similar to fasting. The first three days showed dramatic results in my external appearances. It's my understanding the first few days of a fast are when I release the bulk of the toxins and each day thereafter I go more deeply into older debris, injuries and toxin stock piles.
I will continue to experiment with smaller bursts of this powerful treatment as I move closer to my Juice Feast. I think it would be a powerful prelude (the three days prior) to my Juice Feast. A modified version of it (read: no niacin!) might also be appropriate during the Juice Feast.
My new philosophy from this is that I have discovered pursuing my ultimate health should not be about resolving an issue which upsets me but living up to who I can truly be. With this approach I simply release and allow the issues to resolve themselves.
