Should get as many doctors on board as possible. My doctor considers me a non smoker now. They know the truth. Especially when they get out that stethoscope and my chest does not sound like a deck of cards in a bicycle wheel. If there are a 100,000 pv users and there doctors all see the difference that mine has seen in me. You know, Who better to give all the scientific proof that every one want's than a medical doctor.
