I second weirdtoes' post, and also add that some supplements that may help you could be algin, vitamin C, vitamin E, selenium (in the form of selenomethione), and possibly B complex and magnesium.

With that you may find adjusting your diet could also aid your immunity and reduce any overload of yeast in your body. This means eliminating sugar/yeast/wheat/gluten from your diet. Possibly fruit and milk and honey because of the natural sweetness/sugars and even potatoes.

However, some people start by simply getting rid of the obvious bad stuff and still consume limited fruit, non gluten grain etc. But others may find they need to eliminate those foods also later if they need to.

This can truly help a lot because it aids your body in absorbing nutrients better and so many people who have toxicity, usually have a yeast overgrowth. It is normal to have some yeast overgrowth in a metal toxic environment, but feeding it beyond that point with sugars and junkfood in the diet can be a recipe for disaster.

I would not use antifungals, they can be very risky. They act by splitting open the yeast cell walls when they kill them. if your yeast happens to contain any toxic metals, these will be released back into your system possibly a lot at once. This is why diet is the safest way to go (at least at first). Eliminting the stuff yeast feed on, means the overgrowth begins to die off/reduce and it's done pretty slowly. In act fact, it simply enables your body to do more of what it needs to do and helps the the immune system in the process. It also helps the gut and liver (which is needed for detox).

I would not take any chelating/detox agents for mercury at this point becuase you still have amalgams. Doing so now might lead to an unnecessary worsening of symptoms. Better to wait till they are all out before you try that. For now, the best thing to do is remove as much other toxic load as you can via diet and using supportive and protective supplements. Algin acts like a sponge and can help mop up any mercury it comes in contact with, but it does not chelate. It will not pull more mercury out of your tissues.
