Your motivation for giving up smoking should be to give up smoking and nothing else. It's a pointless exercise with absolutely no positive aspects to it at all. Any sense of enjoyment from your last cig is simply stifling the cravings it causes you to have in the first place.
Try burning the equivalent amount of your hard-earned cash that you'd spend on them in a week and see how that makes you feel, because that's basically what you are doing. Only by directly burning your cash you aren't inhaling as much noxious crap.
