Have to take EtG test today will be around 85 to 86 hours since last drink although I drank a lot. Been drinking a half gallon to a gallon of water a day and taking b12 niacin and mends one a day vitamins I also have worn layered clothes to work and I have been sweating a lot

Over 78 hours is usually sufficient to eliminate EtG regardless of amount consumed. There are however cases where heavy, long term drinking, has been detectable for around 96-100 hours post consumption. (Beck, et al 2007) (http://alcalc.oxfordjournals.org/content/42/4/321.full) However, the 80 hour range, so widely promoted, is in fact a rare exception and derives mostly from Detox studies of chronic alcoholics. (Wojcik & Hawthorne (http://alcalc.oxfordjournals.org/content/42/4/317.full#T1))

Please let us know the results.
