i drank water like mad for the 7 days with a 7 day cleanser yesterday (day 6) i took a test around 5 after drinking tons of water all day and peeing like mad i passed the test. well today and this stuff was supposed to clean you out after not drinking very much water and peeing very much I took another test and it was dirty. so I think it was the water and peeing that made me pass yesterday. JMO. good luck I have my test tomorrow too.
