1: Always do the dillution even if your really sure your clean. Just a little added insurance.
2: I am really leary of any of the detox drinks. All they really seem to do is use the dillution trick. They always want you to drink lots of fluid before the test. So is it the dillution that did it or the detox drink? Impossible to tell.

The strip test will be a good indication in the morning but just because you come up positive there doesn't mean you're going to fail in the afternoon so don't get overly stressed.You already tested negetive in the afternoon.

This is why I'm a big advocate of synthetic urine. It releaves almost all of the stress in these situations. After this if you have the opportunity pick some up and practice with it and save youself going through a lot of stress.:thumbsup:
