If you are serious, I wish you well. If you want to quit, you can. But you need to consider yourself a Non-Smoker from now on, and you will be all right.
I have quit a few times already, I'm just off the wagon for a while. Something always happens that gets me smoking again, then next thing you know you can't put them down.
I don't smoke much when I'm sitting in the house, just when I'm driving.
