I'm amazed that so minimal a round of Diflucan did the job. The sinus thing coinciding with eating (or in my case, the ingestion of anything - ozonated or any water included resonates too well.
The leaky gut thing takes time. The dudes perforate, and it takes time to heal all that. Now I see where you were going with the glutathione. But the body really can't do much with GSH in supplemental form. Recently was told by this dude
that he's seen success with using sublingual glutathione with his patents. I'm nebbing it currently and diggin' it. Your leaky gut is my leaky respiratory tract, and it's been incredibly helpful in improving my lung function. Hoping it will eventually produce the same results with sinus tissue.
I'm sure you already know about the benefits of lecithin and other phospholipids.
Otherwise, sounds like you're out of the weeds and I cannot overstate how HAPPY I am about to hear about your LOSS!
