That happened to me toward the end of my 22 day cleanse as well. I did the swf, and while before it would sometimes start working before I even got it all down, that day - nothing. I bloated up from the salt, could feel it / taste it coming out of my pores; it didn't expel.
I don't know the whys and wherefores. I figured it was my body's way of saying, "Enough."
Congratulations on your successful cleanse, and best of luck to you as you continue your journey!!
