I have one of his books called "The little book of Quitting"
http://www.amazon.com/Little-Book-Quitti...7577&sr=8-2
Basically it unpicks all the lies you tell yourself to keep on smoking. As a smoker, you'll hate it; as someone genuinely wanting to give up, it's the best thing you'll ever read. I have it in my pocket, and hope I'll reach for it next time I'm tempted to buy a pack.
I haven't been to a bar/club or been drunk yet, though, and it's those social situations which will be harder.
I also think starting to exercise a lot more should really help. If you spend all day in front of a computer and don't exercise - like me at the moment - it'll be harder.
