I"m taking it tomorrow morning. It's just after midnight now, and I'm going to go do the test tomorrow morning at 7 or 8ish before I have to go to work at my current job (the one i want to leave for the new job). Sorry for the misunderstanding - it's not after-the-fact yet.

I'll drive to Walmart and get one right now and I'll post back to let you guys know.

How much water would I need to be in the clear? I do about 4-5 hours of walking every day, and drink about 3 bottles of water throughout each day on average.
