Well, its scary because in your case, most likely, you will need to have really dilute urine to pass the test, since you smoked only 48 hours prior to...

Omni clease and those other magic potions are just an expensive way of dilution. Most of us here do not recommend them and do not think they work any better than following the dilution sticky.

What's in the yellow pills? Most likely they contain creatine and B2 along with some fancy thistle or other stuff. Creatine needs to be taken a day or two before so it has enough time to manufacture into creatinine that is found in your urine. Maybe the 4 pills you took the day? before are gonna make it tho

How much water did you actually drink before the test? Here's where the gatorade would have been better, it helps keep up your specific gravity, which is the other test they use to test for dilution (besides the creatinine).

What are your chances? I'm not sure of your size or metabolism. Still, I'm not optimistic, but there have been people posting some crazy results, smoking right up to the test and still passing, so maybe you are one of those lucky people. Good luck!
