not sure if I can do that either its considered a violation if my urine is diluted, or if they find anything in it. Me thinks Im royally screwed. If its diluted its an automatic violation because they assume ur covering something up. This is the worst damn program Ive ever seen. I mean Ive never heard of such BS. OH yeah and they are random tests. I have to call everyday and if my letter or color comes up I have to go. The letter is for alcohol testing, so I cant even use mouthwash unless its alcohol free! Or chew gum or smoke before I go for that. The color is for drug testing. And from my little time on this shit they call u when ever!
