knotme66 yeah my first post was confussing because what was really going on was that i was going to be 8days clean which i was before my test which was yesterday! and i was freaking becaused i just failed 2 home test trying to dilute one i failed 1 day before my test and the other 1 hr before the test (oh shit! & almost in my pants!) but i was keeping track of my voids and this was my 5th one starting thinking about certo then the thought came to me if this does gel my bladder then it could shut down other organs WTF was i thinking!!! by now i am saying ok if its dirty so be it the drive was 30min stopped twice to pee by the time the u/a came my 8th i was ok ! so in my mind this was very helpful even if it was after the fact you were so right dilution takes time
