I have a quesiton. I have been sober for 2 months now because of my probation. I get ETG tested every Monday and Thursday of each week. I can go in at anytime those days. So my question is if I drink on a Thursday night and stop around midnight will I be positive on Monday? The clinic closes at 630 pm. I am 5'4 160 lbs. Like I said I haven't drank in over two months and Im pretty sure Im a light weight now. If anyone could answer it would be greatly appreciated. Thank you.
