Alcohol activates Gaba neurotransmitters that are shutting down your hypersensitivities reaction taking place in your limbic system (Brain).
White tongue is the results of hypersensitivity to food, yeast, chemical or mold. I can shut down all my hypersensitivities reaction by either drinking alcohol or taking DHEA hormone, both of which are stimulating GABA neurotransmitters.
Same as in your case,I relapse 24 hours later but for the initial 24 hours I am free of all hypersensitivities symptoms (to candida, yeast, food or chemicals).
Your smptoms are immune related and are activated by a malfunction of your limbic system caused by heavy or continuous toxin exposures (candidatoxins for instance).
