If it was that easy for you with just the candida diet and green foods and no antifungals it sounds like you just had a yeast problem and not a systemic fungal problem. You can't get rid of the systemic kind that easy. It's very DIFFICULT.
I've done the candida diet for years on and off and still have it even with taking natural anti fungals. I realize I have to be more persistent with treatment of both the diet and supplements. I'm finally turning the corner but still have miles to go. Before I gave up too easily when I didn't see results. You have to keep trying. It'll break your bank account but you have to keep trying.
