no problem. like I said, I'm sure you'll be just fine. If you haven't smoked in a while and you're drinking plenty of water, you should be good ot go. I think those drinks tell you to take it a few hours before the test and I beleive you have to pee at least twice before the test. Just make sure it's not the first pee of the day. I've heard that's when you have the best chance to test positive. And allthough they don't watch you pee, they do make you emtpy out your pockets. I got around this by wearing some swimming trunks under my jeans. I put the sample in the pocket of the trunks and emptied my jean pockets and just dumped the sample into the cup. Good luck. Let us all know how it went.
