I'm getting drug tested tomorrow at 9 AM, help me out please!

So my boss walks into our office today and says "Good news guys! You're getting paid this summer instead of working for free. We'll fill out the paper work and do the drug test tomorrow." This is a mixed bag. As some may remember, I was wondering if I was going to get drug tested when I started but then relaxed about it after I started and realized I wasn't (until now, since we get paid). I have been cautious since then, but took 2-3 hits about 5 days ago. I'm taking 3 Goldenseals tonight and downing about 4 liters of cranberry juice. Am I going to pass this thing? The last time I smoked before those 3 hits was about 2.5 weeks ago and the test is a urine sample.
