Antibiotics also upset the GI flora, so using a good probiotic and/or yogurt/kefir may help. Some people may need a Candida cleanse (NOW makes a good one). If you are eating sugar and lots of carbs, you have to stop this while doing a Candida cleanse as Candida grows on sugars.

If you are drinking alcohol, you have to stop. This along with Candida makes aldehydes as metabolic byproducts, which damage nerves.
