My situation and past experience

So I have to take a piss test for pre-employment drug screen on Thursday. I last smoked Friday thru Monday thinking I was going to have at least 2 more weeks but they surprised me and now I have to do what I do best, pass one in a limited amount of time. This time I went to the head shop and asked the guy for the best stuff he had and he recommended Instant Acting Complete Body Cleanser.

I am 6'0" 180 male with an above average metabolism. I've passed many drug tests in the past (usually only abstaining for slightly over 48 hrs) using the Vales 1 hour formula drink.

Now I know how the drinks work basically diluting your sample by making you drink lots of water while at the same time giving you creatine and vitamins to keep the sample accurate. But I wanted to get some more input (preferably from Fake boobs and N2) about some of the things suggested on this form about dillution.

1) What exactly does the aspirin do or add to the sample? Tums/Rolaids? Since I am taking the cleansing drink should I still take these things?

2) Is there anything else I have to worry about besides urine color and creatine levels when dilluting? I took three creatine pills today to increase my levels and ate a burger. Hope that helps.

I plan on drinking as much water as possible to make sure it's diluted, but also drink the cleansing drink and do whatever else is necessary to make sure my sample is accepted (such as creatine, b vitamins, aspirin etc). Any other recommendations would be great as this is a huge job opportunity for me.
