True you cant actually just remove it.Smoke a blunt and go to the gym and sit in a sonna or however you spell it,that makes you sweat alot.Buy some cranberry pills to take with that gallon of water youll need before the test,also some b complex.You can find these at wal mart or dollar general anywhere.The cranberry things are in the grocery store where all the vitamins are,or you can buy a urinary tract medicine called AZO's cranberry,they are the same thing.I would just buy some b complex vitamins and normal cranberry pills to pop with that gallon cause cranberry juice is kinda nasty.Unless you wanna be a guinea pig and mix it with vodka?
