Clifton,
there is no conflict here as if you have candida then you almost certainly have a toxic liver (along with a whole host of other symptoms).
If you want a definite diagnosis for candida there are tests available. A home-made very reliable test is to take an enema (a bucket set-up only costs $20) with something like Apple Cider Vinegar (or any kind of vinegar). Use about 3-4 tablespoons to 2 quarts of water. Hold it for as long as possible (5 minutes?). Now evacuate. If you have candida, you should see it floating in the toilet as white clouds.
Willpower will certainly help, but you also need other qualities to get you through this. Ingenuity, creativity, self-belief, dogedess. And a whole lot of luck.
