I was at my peak of health when a nice home I both worked out of and lived in developed an unseen severe mold. After I became too ill to walk or otherwise care for myself, I aprroached nearly dieing thanks to Black Mold! About 3 years later or so, I finally came to realize that I had also developed MCS = EI. 14 years later and it can still hit me so badly that I'm sick 2 days later from a bad exposure, although my MCS has diminished significantly.
Consider getting either Ashok Guptas or Annie Hoppers DNRE program; both are available on dvd and both have a money back guarantee. From what l have read many people think the Gupta program is a more detailed program, which l agree with - but both programs havce helped many people improve their health or MCS. Then again, it's also not a 100% success story...
