Just wake up tomorrow and don't smoke anymore. It is just that simply. Just think you can quit something like smoking and you will stop. But you need a strong will to do so. Without strong resolve you will fail.
This is why addicts go to rehab (talking about drugs and other things which are worse than smokes). Because you can just wake up and stop.It doesn't work like that, you're talking nonsense. I know because I smoke from time to time.
First have the strength to want to stop. Second seek support. Third stop buying or asking for cigarettes.
The willpower to resist even when you want it very badly.
