Okay, first of all you may want to be ready to feel sick, but you need to drink at least 3 gallons of cranberry juice a day, in between you need to drink Just as much water, eat green foods, Especially eat carrots, pee at least 3 times before the test and don’t drink sodaTake some vitamin b pills can get them at walmart. take at least 3 a day. You can also drink a lot of coffee in between, but u don’t want to dilute ur urine to much because than they can tell that your trying to flush your system out, Exercise and sweat a lot i would say at least 4 hours of sweating than take a break and do another hour. a day even the day you have to take a urine test. well that’s what I did and hope it works for you by the way bleach and pickle juice doesn’t work its all a fake.
