I have experiend the same thing with Candida and the MC. I do not have any adverse Candida reactions on the Master-Cleanse and in fact, feel much better. When I return to a "normal" diet, my Candida flares up again.
I am starting the Master-Cleanse today, again, and this time, when I am done, I will go to a Candida diet.
Understand I am not recomending the Master-Cleanse for people with Candida. I am only saying it has worked well for me.
