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?
