Noni it's sooo worth it just keep up a mental chant that you can do this and if you can do this you can do anything. I live in NYC and they have this quit smoking commercial that I don't know if it's national commercial but it should be it's of a man who lost his voice box to throat cancer I love to sing while I cook dinner evry night I didn't want to lose my voice or any other part of me to cancer, I also have a son whose 5 who I want to see grow up (most of the time

) Find your motivator and keep it in your head as your mental chant. I'd say once I hit the 6 month mark I knew I could really do it because I had to actually stop and think about how long it was that I had quit it'll be a year for me on June 12th and the year flew by..
Cheers and keep up the great work
