Well I have been fighting fungus for awhile and the only thing that worked was systemic antifungals. I just started two weeks ago with the medicine and sticking to no sugar and the change is amazing. It's like a switch on my brain was turned on. No more anxiety, ADD/OCD/autistic thoughts, and my depression is gone too.

I did however have a very severe fungus infection, with my tongue completely white from oral thrush.

If you have a severe fungus infection, try systemic antifungals.
Olive/grapefruit seed extract/dieting and other natural supplements did nothing for me
