I am a 24 year old female at 5'6" weighing about 130. I drank six beers about 53 hours prior to taking a surprise ETG test. I drank tons of water over those two days, took niacin pills, drank 3 strong cups of Green Detox Tea for the liver and kidneys. What are my chances of passing this test? I am very worried and am positive I will not put myself in this position again. Thank you.

It's a grey area, at 53 hours it really depends on your metabolism, something that can't be gauged just by weight, height, sex and age.

You may fail for dilution, because of the excess water, and pills.
