Job interview today, and no money for test kits...

I got a call yesterday for a job interview today. I've been clean for two weeks, give or take, but I have failed a pre-employment test before (4 years ago) so I am scared to death. I really need this job. I have been drinking pepsi, as I am a huge pepsi addict, and I also bought a bottle of cranberry juice last night and chugged half of it in 20 mins. I am finishing up the juice and also drinking water....
Am I going to be ok? I am so worried if I don't pass the employer is going to call my school and tell them to stop referring me! Any advise welcome and appreciated~

Read the dillution sticky and follow that the morning of the ua. Don't load up on fluids days before, just the morning of the ua. And use a sports drink like gatorade instead of water.

Most excellent!!! Can't thank you enuff!! BTW, this is a nice set up you all have here! Nice to have somewhere to go to talk to people I can trust about these issues. Thanks again!

So, I think I got the job, but havn't been asked to test yet, doesn't mean it won't happen tho...will let you know if and when I pass, staying clean until then.
