I have a pre employment test tomorrow at 3:30pm and need a bit of advice, here's the back story

I'm 5'7, 140lbs, fast metabolism (although it has slowed the past few years, just turned 40) and have been a heavy smoker the past 25 years or so.
But over the past 2 years I've cut back quiet a bit due to my own "economic downturn"
Found out on Wed the 29th I would have to take a SAP 550 W/NIT by 5pm on Fri. 1st
The BAD news is I smoked a bit on the 27 and 28th. (3-4 grams and had not smoked for a few days before that)
The GOOD news I was able to get the test moved to by 5pm on 6-4 because I work fulltime and this is for a part time job and they understood I was unable to get time off.

So the Wed. I found out about the test I started drinking water like a mad man and ran down to the local headshop and got some Detoxify Green Clean not knowing that this was most likely a waste of water/money (I had not found this wonderful site yet).

I found out Thurs that the test could be moved to Mon the 4, so on Fri the 1st I Drank a normal amount of fluids and took a ATHOME drug test (from walgreens) that night around 9pm AND PASSED. (used mid stream had a light yellow color)

Did some more reading and found out you should test 1st thing in the morning so Sat drank a normal amount of fluids and got another test to take Sun morning. AND FAILED (went right in the cup darker yellow) And by "failed" I mean the line was so light that if I was a parent testing my kids I would have sent it off to the lab to confirm.
So of coarse I'm kinda freaking out Sunday and I went out and got 2 STAT 1 panel tests and again the line was so faint it's hard to say there was a line.
I understand that any line no matter how faint means negitive but when I say faint I mean it was really hard to see.

So after all the reading I've done here it looks like the Detoxify green clean is just a dilution method and I'm wondering is it ok to use that instead of the B-12 suggested in the dilution sticky.
The instuctions given to me at the headshop were to drink the green clean wait 15min then 32oz of water about a hour and a half before the test.
Very similar to the steps in the dilution sticky
Any thoughts or advice would be helpful

P.S. Due to lack of time, money, and "clean" friends, subbing is not really an option at this point.
Many thanks in advance
