This is an interesting 5 min video about yeast problems from Dr Mercola:
His remedies will prob be too strong for ICers (boric acid) but v. interesting what he says about women with yeast overgrowth suffering from multiple chemical sensitivities and that they should stay away from chemicals due to impaired detoxification pathways. If u read his download: "Paints, household cleaners, perfumes and scents may also cause allergic reactions, and chemical sensitivities are very common in people with yeast overgrowth".

.Also, he mentions emotional aspects."Once Candida overgrowth occurs, its toxic byproducts are regularly entering your bloodstream. Two of these toxins are alcohol and acetaldehyde.....Acetaldehyde also reacts with the neurotransmitter dopamine, which is why people with yeast overgrowth often experience mental and emotional disturbances such as anxiety, depression, poor concentration and feeling spaced-out".
