chelating with weak adrenals is questionable also dont need provocation/chelator for urine porphyrins good luck

The adrenals are tired because of both the immune activation and the toxin overload. You need to strengthen the adrenals thru nutritionals (I have my protocol which was taken from Adelle Davis on my forum at
http://pptu.lefora.com/2010/09/21/this-category-will-explore-the-body-systems...
this is also very similar to Dr. Lam's approach.

I wonder about the sulfur reactions as alot of food naturally has it. Methionine, cysteine and taurine (and of course glutthione) all contain it.

It is important to use both a provoker and a 'vacuum' while doing detox. A provoker does just that, provokes mercury out, the vacuum sweeps up the mercury to pull it out of the body. Good vacuums for me include zeolite (see naturopath4you.com/silver fillings) for a reasonable priced zeolite rather than waioria (sp) also like chlorella and using charcoal in bulk (see
Tom Harrelson) along with fiber products such as psyllium, flax seeds etc.

Mercury detox (and all detox) is processed by the liver which then puts it into bile for elimination thru the colon pathways. It is important to keep the liver open and to take a binder or vacuum to sweep it out of the colon so it does not recirculate in the body, otherwise you will just retoxify the tissues you just cleansed.

I had good results with several people using Dentox homeopathic from ProNatura. And of course there are other products that may be effective for you I have heard good things about Modifilan as well.
