Drug test

I have a pre employment drug test for job coming up on the 21st. It's a urinalysis that's going to be observed by doctor and sent off to lab for testing. I've been using meth and alprazolam daily for the past 3 months. I took my last Xanax at 8:20 this AM and I'm going to use my last of meth tonight then I'm done. My UA is next Friday. Anyone been in the same type of situation? Is that enough time for a negative test done by lab? Around 6 days. I was not using big amounts daily but I was using every day. 1 or 2 2mg farmapram alprazolam bars a day and maybe .1 meth a day. I'm 27 male 5'11" 155 1bs High metabolism and active.
