If you are sensitive to many different antifungals, and also sensitive to sulphur compunds such as broccoli and eggs, then then you are likely molybdenum deficient.

Molybdenum is needed for the enzymes which detoxify aldehydes and and the enzymes which detoxify sulphites. My guess is that you are also probably very sensitive to cigarette smoke, diesel fumes, and many perfumes. These contain aldehydes. Candida produces alhydes, and many aldehydes are released when candida is dying. Imo you should try taking 500 mcg a day of molybdenum and see if after a taking it for a week or two your reaction to garlic and the other antifungals, as well as sensitivity to perfumes, diesel fumes, and cigarette smoke is diminished.
