I drank about 8 beers on a Friday night and had to take an EtG test the following Tuesday at approximately 72 hours after bac would have been 0. I drank the day before as well. I drank about 2 cups of coffee and 1 bottle of water before the test and urinated several times before the test. I'm 5'5 and weigh about 165 lbs, 26 years old, male. Any advice would be helpful.
