HI Aaron, as far as I know, many tests do not always show candida etc and a person can think they don't have it and they may well have it.

the best test to see if you have a problem is the diet and see if you get a die off effect, which will mean you definitely have yeast problems. Die off usually consists of, extreme tiredness (sleepiness), some headaches, heavy eyes, sore eyes, a feeling of being fogged, dizziness, a feeling of almost being drunk (because of the yeast releasing its alcohols into the system), etc.

That's just another suggestion for you, if nothing shows up in tests and you still can't get any relief, this might be a last resort.

It is highly possible that your body is definitely trying to detox mercury as well.
