You had 8 drinks and you think that will be out of your system in 60 hours ago to take an ETG test?
Ok, technically it depends on the alcohol content of those drinks - but 8 drinks is quite a lot to consume, so if your metabolism is slower than usual you stand a chance of failing.
What I would do if I were you would be to grab a big bottle of water and head down to the gym and hit the treadmills.
Try to burn all that alcohol out of your system, it'll come out in your sweat, and the water will help keep you hydrated but also flush all that alcohol from your bloodstream.
If you follow these instructions, then you should be ok to pass the ETG test within 60 hours.
