I have been using nystatin and feeling better with just 1 week of use, but it is just a gut antifungal

I have also been using olive leaf and grapefruit seed extract, but they probably also only work for the gut

To clear all the fungus in my system I would need something like diflucan but it is too expensive
Is the other only option to clear my system dieting and waiting a few months for the fungus to clear with my current setup?

would like to know that as well, any natural antifungals that would cross the blood-brain barrier ?

A great product is Fungal Defense. It's made by Garden of Life. You can find it on the web at www.gardenoflifeusa.com
This product works great and every so often I go on a treatment course of it and my intestines and body over all gets better. I can really tell when I need it is when my dandruff flairs up and my stomach gives me problems. My wife had a toenail fungus infection and was told by a foot doctor about taking an antifungal prescription and she declined because of the side effects(liver failure ect.) and decided to go the way of our naturalpathic doctor and used fungal defense by their directions on bottle. Her infection went away completely within a short time. The prescrition medication would take many months and only had a 60% success rate.

Two of the best anti-fungals I know of are:

Olive Leaf Extract

Yeast-Fungal Detox

Hope this helps,

Nystatin only works on the digestive tract since it is not absorbed. Graperfruit seed extract and olive leaf extract are absorbed. You could also add garlic, cinnamon, and oil of oregano to your antifungal regimen. Those are also absorbed so they will work on the whole body.
