Worried Sick!

I have a test in the morning and bought a bottle of Qcarbo32. I'm worried they will make me wait to long for it to be effective(if it is indeed effective to begin with). I read it is good for 5 hours but do not trust it completely. Are there any ways I can increase it's effectiveness or window of cleanliness?
I also had my nephew pee into a condom and was wondering if it will be warm enough if kept between my legs until the test. It will be 4 full days since I have smoked tomorrow morning. This is an instant test and will not be sent away. Any suggestions?

Someone help put my mind at ease!!!

my friend drank half a oz. of vinegar the night before and it worked and lots of water. iam doing the same man. good luck.

HAHAHAHHA, YOUR NAME, I can't stop laughing.

Well, I passed!

I took in someone elses and kept it between my buttcheeks until about 20 minutes before the test. I then filled a cup with hot water from the water cooler at work and warmed it up. I put it back between the cheeks for about ten minutes and took the test. It was 97 degrees. Talk about luck! It's a good thing I didn't rely on dilution or the Qcarb32 because they made us wait 8 hours from the time we got there until they tested us. I dodged a bullet this time.
I know I have said this before but I think I'm going to take a bit of a break from smoking because they radom quite regularly and I can't afford to loose this job.
