Pepe, I just read your post below and I decided I'm going to do exactly what you are doing. I'm going to end my Master-Cleanse with a 7 day Oxypowder cleanse. I ordered it this morning.
Here is how I plan to do it:
drop the SWF
take the Oxypowder
continue the lemonade
continue hydrating properly with water
my only question is about the LAX tea. Should I discontinue the LAX tea? Is my plan the same as what you are planning during your oxycleanse portion of the MC?
