hey man, im on felony probation and have passed 20-22 times now for the year with a detox drink, the reason i failed 2 times was because i ate food thinkin that i had to for some reason, well thats bad, the new directions on there tell me not to eat dairy, caffeine, or food 3 hours prior to testing. you will drink the drink, wait 15 mins and fill back up with water, drink that, and wait bout 5 mins and just drink about 2 more bottles filled back up with water if u can. piss about 4-5 times. then on ur last one, i like to piss just a lil bit and hold it till i get there. Just make sure that ur piss looks clear on the last two times u piss. itll look clear when its goin into the cup for him, but it will quickly change color from the creatine and vitimins. Basically meaning that it will be diluted, but ur creatinine levels will be up and thats part of the test. so it wont show up preliminery or somethin. If your over 200 lbs, id drink 2 drinks. LOOK FOR THESE AT LOCAL GAS STATIONS OR DRUG STORES, NOT GNC, IF YOUR ARE PAYING MORE THEN $30 DO NOT BUY IT, THEY ARE ALLLL THE SAME, NONE OF THEM ARE BETTER. if u need help tho, PM me, good luck
