sbudda!!! that is exactly how i stopped!
after not smoking for a week cos i couldn't i didn't see any reason in starting again cos i was over the worst of it. mind you i did have a couple of sudo-panic attacks but nothing too bad really.
it is hard to not have the odd one when out drinking but i've stopped even that by getting into fitness stuff.
the other thing i found helped was everytime i wanted to smoke i imagined all the disgusting things it does to your insides... and i really went to town on this, imagining dripping oozing lumpy tar in my lungs and open sores in my throat and that kind of stuff so that i really didn't want to do it.
i think i perhaps went too far though because now i have little sympathy for disgusting diseased smokers sitting killing themselves and others because they think they look cool
another way to stop would be to move to scotland in the next couple of years cos they are banning it from public places!
