Right on Simon! I have been doing the P&B also using Dr. Schulze 's formula and it has been great. I totally agree with everything and also like what you said about the warm water - that seems to make sense as cold water can sometimes be a shock to your system since it is lower than your body temperature.
Also, I think it is really important to get your bowels moving regularly (2-3 times a day) before doing the P&B. This puts less strain on your bowels and makes the P&B that much more effective.
What worked for me was doing Dr. Schulze 's Intestinal formula #1, which was a godsend. He recommends to do that before the P&B, and it was great for me. It's all natural but very very powerful - you start by taking one pill with dinner and increasing each evening until everything's moving. Once you've got the traffic moving, so to speak, then you can send in the P&B to take care of all the old impacted fecal matter, heavy metal residue, and general sludge. Good luck!
