I have never been a drug user, but I am concerned about a recent pre-employment drug test I took. I think it may show that my urine is deluted. I get frequent UTI's, so I try to always drink a lot of water and juice. I drank a 44 oz diet pop right before I went in to take the test, and didn't even think about it because I am used to drinking a lot for the health of my urinary tract. When I gave my sample to the nurse, I noticed it looked really pale yellow. I'm totally freakin out!! Just how much do you have to drink to raise suspicion?
