I'd be very very careful with it. It may work very well or you may have big issues on it.

I was on a candida forum a while back and NAC was brought up for people to use. Someone was very annoyed with the guy advocating it and told him that two people who were put on high doses of it, committed suicide (they were mercury toxic). Now how true this is? I really cannot say. But when mercury is mobilised, it can really cause horrific effects and sometimes suicidal urges can result. I've had it myself from taking certain supplements (though never tried NAC). So I can see how it could occur.

I think Sunshine P talk it too (either NAC or just cysteine) and had terrible symptoms from it which he took sometime to recover from.

NAC maybe really helpful or problematic. So if you do try it, go very slow and check for any concerning reactions.
