Hi Tophat...I really don't have any experience with Schulze's formula, so I'm afraid I can't answer your question.
Maybe you could try posting this same question on the Schulze's Forum and on the Bowel Forum...? (also, if you posted a fresh post here with appropriate subject line someone here might help you too!)
And...as for your second questions...That is the fun part! Even though you're not eating any solids, when you do the Master-Cleanse and a Bowel Cleanse (I only know about adding Bentonite and psyllium drinks) - the psyllium scrubs out the old mucoid plaque in your intestines, so you get to see all sorts of icky black/green/grey/brown stuff come out...
