Just wanted to comment on the yeast issues. We are in the same boat. We have yeast overgrowth that we have been dealing with for years now. Cannot get it under control. We have been gf/cf, dye free, SCD (that was hard on my son!) and used digestive enzymes. I have not ever been able to do a low sugar diet which I know would be helpful... but my ds is 4. It has been hard enough to work with the other stuff.
ANYWAY, we had no success with fluconazole so we stopped using that. We finally tried a product called Enhansa. It is a curcumin supplement that is supposed to be good for yeast. We re-ran an Organic Acid test after he had been on it for about four months (well a fraction of the dose) and his yeast markers had come way down. They are still not in range but they were significantly down. His doctor didn't think this could be from the Enhansa because we are only at about 1/8 of the dosage... but we have not changed anything else.
We just started an antibiotic with Dr. Latimer so I am worried about the yeast. I am trying to increase the supplement but I am not sure what is going to happen. The die-off reactions can be bad as I am sure you know. Just another piece of the puzzle!
