The thing that has amazed me about this fast (my third in the past 6 months) is that brown (sometimes solid) stuff is still coming out of me (day 23)!! Yikes! You might want to consider going longer this time and see what happens. It's my opinion that one longer fast gets serious stuff done as far as detox that several shorter fasts simply can't accomplish. And I don't think it's too soon for you to start another one. It does sound like you broke the second fast too soon (probably during a cleansing crisis).
I'm hoping for a pink tongue before day 30, but either way, I'm only doing 7 more days. Hopefully with a clean diet afterwards I'll be ready to just do maintenance fasts once or twice a year after this.
Whatever you decide to do, we're here for you! God bless!
