It wont flush your system. Try certo jell. Its in your pudding and jello isle at your local grocery store its used for making jam. There will be 2 packets of jell. Put one packet into one gallon of water and the other in a different gallon of water. Drink both gallons right before your test and it will give you a window. A time period for you to pass your test but it does not clean your system out for good. The certo jell will stick to the sides of your urinary track allowing no secreations to come threw. It doesnt last for long ones you pee out all the certo jell your time is up but it does work I used it on juveniel probation and a friend did it for a millitary piss test
