Killerweed, I noticed that you are extremely insightful and I would like to ask you a question. I have a physical/drug screen in a week from today i already have QF 5.7 and i am testing getting the temp. correct right now. I was just wondering if I sew a pocket in my briefs to hold the QF, would that go un-noticed throughout the physical? I am just wondering because i am nervous that they will not allow me to put my clothes back on before i take the test. Ive never done it before so i am just wondering. f you could please help me out i would reallllly appreciate it. Just trying to ease my mind. thanks!
