This can be a difficult problem and can take awhile to fix. Dr. Jacob Teitelbaum is a well known Chronic Fatigue Syndrome and Fibromyalgia doctor. You can find his pretty extensive regimen for yeast at the URL below. (You can find his protocol for yeast about halfway down the page.) Perhaps theres something in it for you.
