I cut down on cigarettes by having a fiance that HATES smokers, so I can smoke only when she no-where around and a if I smell like it I get my ass kicked.
Or, you could do what my friend did, go to someone's house where they don't let you smoke in the house, get into a deep conversation with them, and you'll ignore the nicotine craving, eventually you'll have to go outside to have one, but it's a lot longer than you'd think. After a while, you get used to it.
