drug test tomorrow

Ok... So I have a urine test tomorrow, which I found out about today, so I'm kind of panicing here. I'm about 5' 8" and 130 pounds and I smoke about 2-3 times per week.

Anyways, I have a test tomorrow so I went to the local smoke shop and asked what they had for Detox. I bought a Absolute De-Tox from Spectrum Labs which he said only 2 people have said it failed them in 6 years. Well after reading here it seems the drinks aren't the best way to go, so my question is, given the time frame of a drug test tomorrow afternoon what is the quickest way for me to atleast piss clean? Or is there a certain way to drink the bottle that will give better results?

Read the dillution sticky.If your head shop had the detox drinks they should have synthetic urine.Pick some up and practice with the temp as much as you can before the test.
