P&B question (with MC)

I am planning round #2 with the Master-Cleanse and would like to include the P&B shakes this time around. I have read about the possibility of constipation, etc and needing to drink extra water.

A friend of mine who has done the Master-Cleanse with the shakes, says it tastes like wallpaper paste (wonder how she knows that? LOL). Anyhow, my question is can I "dilute" it a bit, add some fruit in there and make it like a "smoothie"?
