On Saturday the 13th, I drank a big bottle of jim beam 80 proof (40%) mixed with dr pepper in a short period, maybe 1 -2 hr. I think I started drinking at 8.
It is the 16th now, and I have my ETG tomorrow at 9AM.
Will I fail?
I have been drinking a lot of water,
I am 6"2 weigh around 220
Please help.

60-80 hours is what most say to rid the body of any trace of alcohol, but too much water is as bad as none. Dilution is a failure too.

Good luck, the test is what it is. Its more about your history than your build. Are you a regular binge drinker?

Help what? We can't do anything. You chose to drink heavily and the test is tomorrow. And the results were ___________?

Sometimes failing means successes later. Think about that.
