Hi everyone. First sorry my english, I'm spanish and am 23 years old. After two years very sick, and after visit many Drs. I´ve discovered that I´ve mercury poissoning. Before that, I believed that all my troubles were produced by candidiasis, but now, that I´ve killed all of them, I´m still sick. My levels of mercury are very high, 12ppm, being the maximun tolerate level 1ppm. I had some Amalgams when I was 13, but now I´ve none. I think they must to have fallen with the past of the time. Now I´m at home everytime because I,m very tired and am not be able to continue my studies. A week ago I started to have DMSA, 250mg per day, and some complements like zinc. My symptoms, as well as the big tiredness are insomnia, blurred sight, nauseas,lost apetitte between others. I have vitiligo since 2000 too. Please I would like Knowing if I´m in the correct way, and how many time can this hell last. And if after expelling the mercury out of my body, I´ll improve or if it will necesary to adjust something like the hormones levels or something similar. I say that because I have a low levels of DHEA. Please answer me if you have experience in this subject because I´m very desperate. Thanks everyone.
