Congrats to you! I have been meaning to stop smoking myself. Very hard habit to break. A few years back I did quit for 9 months and was doing well, wife was proud, happy.
Then a situation popped up that was hard to deal with and started right back. And still smoking to this day and talking about quitting, but so far that's what it's been, all talk no action. I think it may be just as hard to quit smoking as someone trying to quit heroin.
Anyway, keep up the good work and I hope to join you sooner than later
