I was just in a similar situation. I was clean for 16 days and realized i would not have more than 18 days from my last smoke session to stay clean, the hiring process moved faster than expected. i still failed a home test at day 15 (healthy 5'9 165lb at the gym at least 4 days a week) still failing after 15 days and drug screen on day 18, i am subbing no matter what! I got a friend going to donate on day of test, i practiced walking with 3oz bottle of water in the taint with a hand warmer, held a temp of 99 -100 for 2 hours cositently after microwave for 10 seconds. i was checking temp with digital thermometer I am sold on subbing, as i cant risk dilution failing a home test so close to the real test.

If you only have 29 days dont risk it, unless you pee first pee of morning clean for 2 days in a row, (doubtfull)

Just sub and start smoking again...

My only concern is the bottle can make a splashing noise in your pants when walking if not carefull. I am using a small bottle similar to travel shampoo.
cdk420 Reviewed by cdk420 on . Waiting + Dilute or Substitution Hi Everyone, This is my first post but I have been lurking here for the past few weeks. I am a healthcare employee, and have recently been offered a position at a hospital about 45 min closer to my home. I recieved the call on September 27 and have not smoked since then. I am 6'5 235lbs and fairly active as I am performing procedures on patients all day. I smoked every night when I got home from work and went through about a 1/4 every two weeks. Quality wasnt very high, just regs. My Rating: 5
