I would say that whatever ongoing infections you have get worse after exposing yourself to mercury fumes or other toxins like cigarette smoke (which consumes glutathione for detox). The body needs all the glutathione it has to keep things even somehow under control in your body (the immune system needs it badly for its functions). So definitely don't ever smoke, drink soft drinks that contain aspartame etc, and don't eat or drink anything other toxic that uses up too much glutathione.. I'd say your slow phase 2 liver metabolism is at least partly a consequence of having too little glutathione around for detoxing. Have you tried supplements that make phase 2 work better (glycine, NAC, taurine, etc.)?

I'm also seriously starting to get interested in molybdenum/panthetine for detoxing aldehydes from candida, because I tend to end up in a half-drugged state, for a day or two after using lots of ALA, the toxin release is that big.

Often the supplements which makes us feel better are those which gets liver to work better, because it is the organ that is most heavily involved in detoxing.
