I am super sorry I know I have asked a lot about ETG tests, but I'm curious-Does the 80 "cut off" START on your last drink of alcohol? Meaning if you are withdrawing is that when the 80 cut off is happening? Or Does it happen when you are all done withdrawing? Thank you-Im a bit confused on when the "80" actually begins. I've heard its when you had your last drink and I've heard its when your actually a .000
