Hi I'm kind of new to this probation ordeal. Well I last drank 4 to 5 shots of fireball on Friday and had one beer and stopped drinking around 11pm.. Its been 68 hours from last drink on Friday up until my ETG screen that was given at 830 on Monday. I drank a lot of water on Sunday And all day Monday even up to the hour of testing. What's the chances of coming back positive?
