Replying to Not falling asleep to pass a drug test

Well, unfortunately, I have a drug test coming up tomorrow morning and a dude is going to watch me pee. As one realizes they are probably doomed they start to come up with dumb solutions to save themselves. My logic here is this. When you sleep toxins naturally build up overnight as your body is resting, thats why you need to pee in the morning. My drug test is first thing in the morning since I'm going in before school. Would staying up all night and drinking water and coffee help my efforts to not get in trouble? Help me out homies with any tips as this might mean less skiing depending on the results.
