You may also want to add aloe vera juice, l-glutamine (both help repair the colon wall), and Primal Defense. If you have never heard of Primal Defense, the best thing to do is to do a google search on it and read about it. IMHO, it's one of the most important products you can take if you have candida issues. The cheapest place to get it is at several places, but you can try: www.thevitaminshoppe.com
But be sure to read as much as possible about the product; it's much, much, better than regular ole' probiotics, and accomplishes so much more, too. It will help get the candida under control, and you should take it at a different time than you take the Nystatin.
There is a post on Andreas' forum about how flushing the liver can help get candida under control because bile is important in cleansing the colon of bacteria. If bile production is impeded by intrahepatic stones, then that means that the bacteria cannot be cleared properly....this contributes greatly to candida overgrowth.
I hope that helps. You can do the liverflush at any time, just be sure to read as much as possible about it, and also read the liverflush forums as much as possible so you'll know what to expect.
