I may have to take an ETG Urine Test on Wednesday (3/27/13) and I have a party that I plan on drinking at on Saturday (3/23/13.) I am 31 years old, 5'4'', 155 lbs, female and I plan on drinking somewhat heavily (2-3 shots, 5-6 beers) but stopping around 1 or 2 am. I know the test usually goes back 80 hours so if I do drink, by the time I may have to take the test, it will be 87 to 88 hours. Is this ample time to pass the test?
