Is it possible to really stop smoking, like you've never smoked before?

Yes and no. If you 'try' to stop smoking, you think about it all the time and it drives you crazy. But if you decide you don't smoke, then you might feel a twinge but you ignore it just like you never smoked before.

The answer is to figure out who owns that head you live in and take control. Throw out all thoughts you consider unprofitable and make it think thoughts you consider more beneficial. It's called responsibility. Take it, it's yours!
