Don't risk it, sub! I'm chronik, tried all the dilution stuff/drinks nothin worked, lost a couple a good jobs thanx ta that, now I don't screw around. I use quick fix syn. urin in my urinator, both worth every penny!! just took a DOT pre employment monday, and sittin here smokin while I type !! ya could get by without the urinator, but quick fix is a must,used to just sweat this process out! not any more oh by the way ya might want two bottle's of quick fix, glad I got an extra cause I needed every drop ! collecter split my sample four ways, didn't even put a line on the cup, said give me all ya can then used every last drop!! one bottle would have never been enough, first time for that one. Anyway if ya like food on the table.... sub it girl!!! DON'T RELY ON THAT DRINK THING!!! good luck
