If the symptoms that you wish be rid of the most are not stemming from die-off but the Candida itself, which you seem to believe, then it’s simply because you have a strong case of Candida. It can take a few months for most of the symptoms to disappear, especially if it is a particularly bad infestation. The fact that you’re seeing less of the other symptoms, i.e. your skin and athletes foot, is a sign that the diet is indeed working.
One of the reasons for the fatigue can be the fact that your liver is still working at ridding your body of the toxins being created by the Candida, plus, Candida in general is a drain on the liver as well as other organs. If the blood is receiving an overload of toxins and is not able to clear them out quickly because of weak and/or inefficient liver function, then the blood is limited as to amount of oxygen and nutrients it is able to carry through the bloodstream, which in turn reduces energy production. This is how poor liver function results in constant fatigue. Molybdenum is an essential trace mineral which aids the liver in its functions and may be all it takes to relieve some of the fatigue.
Other than the energy production, the fact that you’re not receiving the amounts of carbohydrates needed for energy production is something that your body is still adjusting to. Eating something like half of a Granny Smith apple twice a day can add some carbs to your diet, as well as coconut flour bread which is filling and nutritious. You can find the recipe for the bread on the forum.
If you will give me the name of your multi-vitamin, I’ll check the ingredients in it.
