I have a month to prepare

[Tokin' White Guy]

I was a casual off and on smoker. The most I would smoke pot is 3x a week since September of this year, recently quitting 2 days ago. I am applying for my CDL license Jan 20th 2006 which requires a drug screen. I will no longer will be smoking and I want to take any precautions ahead of time so that I may clean myself out before the drug screen. I do not believe in those drinks sold in headshops all over the place, but I do have one just in case.

I know of exercise, red meat (Creatinine) before the test, exercise, and B-complex vitamins

Are there any measures i can take to help the cleansing process along? Your help is appreciated!
