I don't know if this little bit of info will help you or not but, the Master Cleanse was originally intended to be a "10-day cure for ulcers". It is very effective. It really helped my acid reflux problems.
As far as candida is concerned, I don't really know too much about that. I wonder if a round (maybe a couple of weeks) prior to the Master Cleanse, of good probiotics could help that. Since I have never had a problem with candida, I'm not really sure. Have you done a search on curezone for candida?
At least search on google for "Master Cleanse pdf". Reading the book will give you a lot more information.
