No one should be obsessing on the idea that "you can't smoke." It is not true, you can smoke. You can smoke anytime you want. You can smoke 20 or 40 or 60 or if you really want to make yourself sick to your stomach quickly, maybe even overdosing yourself into cardiac arrest, you could force well over a hundred cigarettes down today just to prove you can smoke. The issue is not that you can't smoke, it is that you can't smoke one without relapsing. Relapsing means you either have to go back to full-fledged smoking again or go through quitting again. Those are both lousy "options." But yes, using your mind set, they are still options. But you have a new option now, a better option or choice to consider. That is if you don't take a puff, not because you can't but because you choose not to, you never have to go through smoking or quitting again.
So don't let anyone tell you what you can or can't do. But ask yourself daily what it is that you want to do. Do you want to take a puff and once again be controlled by a substance. A substance that "makes" you smoke, and "makes" you sick and if left to its own devices will "make" you die, or do you keep control over your own destiny. To keep that control, never take another puff!'
