I am just finishing up a 21 day cleanse. I broke out a lot and I don't usually do this. Everything has not cleared up completely but I'm still on O.J. and broth. I'm guessing that my skin is just one way the toxins come out.
I'm no expert but I'd be really suprised if you are pulling mercury from your brain. I have a child with autism and have done some reading on chelation. My understanding is that getting the mercury out of your brain is not an easy task.
