I really liked the Schulze program, and will finish off what is left of the product down the road. One thing I dont care for is making sure i get in the required amount of "drinks" per day. (It's 5-6 of the IF#2 per day, plus the IF#1 in the evening) but i did like the results, as i knew it was working.

I have never tried P&B shakes, so i can't compare them

Right now I'm on the Oxypowder program -- nice thing about them is I only take the caps once per day. drawback is your BM's come out as "the runs" -- so keep near a bathroom until you know how it effects you. (that's only the first to second day)

good luck and happy cleansing
