My friend is 270lb 38 year old male. He drank about 6 pitchers of beer Saturday night. He stopped drinking at 2am Sunday morning. Most of the day on Sunday and all of Monday and Tuesday he ate, drank a lot of water and soda pop. He also took a dose of B-12 all of those days. He has an EtG test on Tuesday at 3pm. I was wondering what his chances of passing the test were.
