Well the instant cleanser is something you drink like at LEAST an hour before the test, you then pee at least ONCE (3-4 times is recommended) before you go in for the test. Im aware of the fact that they do not watch you pee, i have thought about using somone else's urine...i'm more worried about keeping the urine warm, which is why i would rather use my own...which isnt clean...which is why im asking about the Instant Cleanser 2. Has anyone ever used this product? Was it successful? Any complaints?
