I just got the Cutler book, really good stuff, I am very impressed how he discusses things. In my case I think I could also have problems with some vitamins, maybe b12 or b12 related imbalances on top of toxicity, since many symptoms I have are neurological and of the metabolism. I read somewhere that Glutathione production stimulation reduces b12 further so now I am thinking that maybe some of the symptoms I had from foolishly taking dmsa could be because of this since as I understand dmsa stimulated the Glutathione production. Now I need to research this too before taking any step. This can be very complicated.
