I didn't realize you were already fasting, sorry. In that case, I would listen to your body. Are you having a candida flare up or concerned based on past issues? If the cleanse still feels good I would continue. If the candida is getting out of control, I would end the MC. You can always come back to it later. Whenever you choose to end the Master-Cleanse following the candida diet may be quite beneficial.
As for the sweating issue, I wonder if Zoe's improvement in this area was increased by her frequent detox bathes. I know when I add ginger (and/or turmeric) to a bath it really opens up my pores (I turn all red and sweat profusely). Perhaps this will help you too. Just beware - the turmeric will turn you and your tub yellow.
