I agree with Bex that things usually change completely when you have ALL of your amalgams removed. I had only ONE, but still got poisoned with mercury, copper and whatever, and im still battling candida now after 9 months of the removal. Before the removal I could eat garlic in large amounts, but now I get nearly bed-ridden for 24h after just one clove of raw garlic (sweating, diarrhoea, burning sensation under skin). Also my fingers got immediately swollen (and they are still) some 3 days after the removal, when all mercury was gone from bloodstream, and the body was able to fight the candida with top perfomance. Before that, the body would just let the candida spread around. Swollen fingers indicate probably that your body is actively fighting the candida.

When your immune system is disabled by e.g. mercury it's likely not to respond to anything, I know persons who have lost it completely, their body doesnt react to anything, although they are seriously ill (CFS, fibromyalgia). In that way I consider the violent reactions of your body to ridiculous things such as vitamins and garlic a good sign that your body is at least able to detox. The problem is just that your burden is great, and your liver & kidneys are not in best shape after several months of this pain.
