You drank an awful lot of fluids in a short time. My guess would be that your urine was heavily dilluted which is why you passed.Try the milk thistle without all the fluids once and see if you still pass.Thats the problem with a lot of the detox drinks too. They make you drink lots of fluid with the detox kit so how do you know whether its the detox that worked or just all the fluids that worked.
