I am having a rough time quitting cigarettes.
Click SMOKE to give in to the urge to SMOKE.
Click DON'T SMOKE to choose not to right now and stay an non smoking ex smoker. You will have to make this choice. You can smoke again any time.
This is your last pack. You thought that last time.
One puff and you'll be SMOKING!

hint.
Click smoke until frustrated enough, then click WALK AWAY to break the game.

I have seen this movie many times and am always extremely moved.
