After all the damn research I had done about passing piss tests I finally came to one conclusion....It all depends on the person that is taking the test. The more I looked into things the more nervous I had gotten. All I did was gave myself 1 week without smoking before the test and drank about a gallon of water a day with 12 cranberry pills. The day of the test I pissed 4 times drank 2 16 oz of water, a Vitamin water, Green Tea and a B-12 pill and some soda. (I had 6 hours before the test because it was late afternoon) All that shit did was give me a stomach ache.
