It nearly impossible to balance the Candida population and digestive functions without removing the thousands of stones congesting the bile ducts of the liver first. I have described your symptoms and their causes in great detail in the books The Key to Health and Rejuvenation and The Amazing Liver Cleanse (www.1stbooks.com). I strongly suggest that you do a series of liver flushes to resolve this problem. The methods you have applied and supplements you have used, do little or nothing to remove the cause of your intestinal trouble; they are a merely able to temporarily pacify the symptoms, just to make them flare up more strongly afterwards.
Candida overgrowth is not the problem, it is a necessary side-effect of poor digestive functions due to insufficient bile secretions. If Candida were not present, accumulated waste would not be broken down and death would occur due to excessive toxicity. Trying to kill off yeast is not only a useless attempt (yeast outsmarts anti-fungals), but it causes nore harm than it does good. Taken away what feeds them is far easier than trying to eradicate them. Follow the directions provided in the books very carefully and you will not just find relief, but remove the problem altogether.
