I was exposed to black mold for 5 years in an office, which, in susceptible individuals, will trigger Chronic Inflammatory Response Syndrome, CIRS. Even after getting out of the mold exposure and going through the 7 step Shoemaker protocol, some damage is not reversible. I have susceptibility to insomnia due to having a mess of GAD mutations, which makes someone very quick mentally, but also predisposes to insomnia, because their brain never shuts off. That would be me. CIRS attacks whatever weakness someone has, so I developed the insomnia from hell that is one of the possible effects of CIRS. This product was recommended by my health coach to help me sleep. It is much less expensive than another product that is available, which I have also used. This works as well or better. It also has anti-cancer effects.
