Well the problem is that when you remove your fillings, your body is no longer sitting idle, and letting parasites like candida thrive & multiply in your body. It will attack them until they are gone, and the task is not easy, the candida is a very persistent lot of nasties.
The recovery time is usually a very long one, even for moderate cases like me, it took at least 6-8 months to feel significantly better, and I believe that for me over a year is required to be completely and fully healed. For more difficult cases, 3-4 years is a more realistic time, especially if you started out with a suicide depression.
From what I have seen here and from other places, females have it a harder time than males when recovering, because females appear to blow up their adrenals more easily and they are also more susceptible to candida.
