I drank 7-9 beers and 4 shots of rum on Thursday evening, still had a bac of .026 on Friday at 10am, blew .000 at noon and tested at 8:40 am on Monday which gives me 68-69 hours between no bac and test. What are my chances passing an ETG test? 6'2 237 lbs male. I also did an 45 minutes of treadmill Saturday and Sunday, sweated profusley, and drank at least two and half gallons of water all weekend up to 10 pm Sunday.
