final update--
just passed a home test for the second time! yay! i don't know how this is possible as i was a chronic smoker (smoked once daily) for months until 6 days ago and i didn't dilute at all this time (urine was fairly strong yellow!). in addition, i run everyday for 30 mins. (including today before my test). perhaps i have a high metabolism or something. well..i'm going in today, wish me luck everyone!
