Hello-
From this story, I suspect that the weight issue (and the insomnia) is due to mycotoxins.
Remember that the body is so smart, and when exposed to more mycotoxins than it can handle, it creates more fat in the body to be able to store these toxins as safely as possible (better to hide those toxins in fat cells than having them move into the fat in the brain).
This means that:
a)while she was loosing weight she was freeing and mobilizing these stored mycotoxins. (Making the insomnia worse again)
and
b)once her body realized that she wasn’t able to handle safely the toxins that you had mobilized already… it was refusing to lose more weight and mobilizing more.
So next thoughts on my part:
-mold toxin binding (however you usually like doing this best… GI detox, Welchol, CSM, etc)
-address the inflammation in the brain due to the “fire” created there by the mold exposure (TA1, KPV/BPC, TB4, melanotan II). Side note here… TB4 directly addresses things we follow in CIRS like TGFB, VEGF, etc. And Melanontan II has MSH effects (also of course, a very important arena of the nasty affects that Mycotoxins have on the brain).
I would personally think of the above two steps first. And I bet her insomnia would improve (brain could stop being hyper-vigilant) and her weight loss might resume.
