i think it's all in your mind, if you want to cut down, you'll be able to do it quite easily. that said, it does help to have some sort of distraction, when i cut down i used to have those travel mints instead of a cig.
you might find though that once you've cut down you wanna give up completely, i know that when i cut down i had every intention of being a social smoker, but you tend to find that smoking doesn't taste the same as it used to, i mean i've only been quit for 3 months and now i'm starting to find that the taste/smell of cigs repulses me, even on a night out.
