Well the detox drinks are pointless IMO. I would try to find a pipe/smoke/head shop and see if they sell the synthetic urine. That would be my suggestion. If you don't have any money to buy the urine then I would suggest you use the detox the exact way the directions explain it. So what stop right now, and drink tons and tons of water for the next 3 days. Then the day of your test drink the detox and more and more water. That is way i don't like the detox because you can fail because it is too diluted or because it just didn't work. But, look into that synthetic urine. I paid $40 for mine and it comes with a temp guage and directions on how to use it. It also lasts for 2 years so you could even have another one handy if you ever get random drug tests as well.
