no d00d don't add anything to it. Also, those de-tox drinks can sometimes backfire, because some tests test for the shit in the drinks. Your best bet is to exercise, and drink a shit ton of cranberry juice and a lot of water. make yourself piss a LOT!
Also, make sure when you take the piss test that you piss earlier in the day. The most toxins come out in your first piss of the day.
