It's a curse that wants to suck you back in. But you know it offers you nothing but poisonous crap. And makes you pay big money as well! Remember Those cravings are temporary, but the benefits of not smoking will be permanent.
Can you at least not have any fags in the house? You can't smoke if there are none there. And don't buy any for Christ's sake. It isn't a question of will power then, if there aren't any to hand, smoking becomes a physical impossibility.
