You could drink over a gallon of water about two hours before test. (This can be dangerous and hard to hold). Eat lots of b12 vitamins for color.
You'll hopefully just piss yellow water.

Be warned to stop smoking. High chances being your test will show negative dilute. They'll probably ask you to retest and on your 2nd round, you better not dilute again.

Good luck.
walnut Reviewed by walnut on . Daily User: Test in 2 days I'm a daily user for a couple years, have a pre-employment screen in about 36 hours. I bought the 'omni cleanse' drink from the headshop, then read some stuff on here, and now am not feeling too confident. Thoughts? Should I try to substitute instead? Yeah, just found out about this so I smoked last about 6 hours ago, putting it at about 42 hours before the test. My bad. thanks Rating: 5
