I have never had to take a drug test but now I am looking hard for more work. I'm curious, my urine is ALMOST ALWAYS clear if I drink my normal amount of water it takes to keep me from getting thirsty. It's only yellow if I do something odd like mow the backyard without drinking or something. Is this a problem? Do I need to thirst to death all morning before a test? How can they discriminate against someone like me who just normally chugs LOTS of water every day? Anyone else have this problem, solutions?
