Reading Dr Poesnicker book and taling to Dr Neville, they both believe that all AF sufferers have candida, because the body is damaged, broken and not working at all.
Once the system is back online, especially the adrenals then the body will start to detox and sort itself out, so I might suggest to stop worrying about the candida, and get the body supported first. This why all the AF specialists dont direct therapy to candida first, it is believed by them to be an aftermath of a poorly functioning system, not the primary.
You will of course crash coming off HC, so dont worry to much about that. It just shows that you havent healed your system enough in the meantime.
Talk to Neville or maybe read Chronic Fatigue Unmasked 2000.
