I haven't got the official word yet from the HR guy, but the testing lady said I passed!!! I was chronic for 30+ yrs. until the 15th of this month and have abstained since then. This morning I drank Strip NC and drank about 3 glasses of water about 3 hours before testing time. I did a home-test 2 hours after drinking it, and it was still positive! yikes! I couldn't back out of the test, so went for it anyways. I peed 3 times before, and the tester saw a faint line, so said I passed. Hopefully I get the call soon that I can start my new job on Monday. The 60 bucks was so worth it!!.
