It can take 10-15 years for your lungs to go back to "normal". There are immediate health benefits because you are not poisoning your system with all the chemical additives they put in cigarettes. You will immediately feel empowered. Use each and every quitting product there is and find a support group through your local hospital. Decide now, what to do with your hands, because that is one of the biggest problems. Lose yourself in Ask and other distractions to keep your mind occupied. Good luck!
