First you need to relax. It will be a urine test and you will prob pass if you do nothing. Just in case, drink lots of water (3 gal a day) and flush your system from now until Thursday (piss alot). The day of the test do not drink lots of water, just normal amount. Piss when you wake up, do not use your first piss of the day for your test. When you take your test, piss out half of your pee into the toilet and use the second 1/2 of your pee for the test....(just incase there is any buildup in your system).


You will be fine.
