Will Power

I don't think will power can help in that situation because it'll be easy to overpower. Try and occupy yourself with other things like becoming a Gamer, study Alchemy, have a Book of Shadows and create a hobby writing in it everyday. There's thousands of thousands of things you can do to stop smoking. You just have to think less of smoking and think more of other things.

Balancelight, I strongly disagree. If your will stays strong, you can quit whatever you want.
I know from experience.

its basically stubbornness when you just refuse to not do what you have set your mind towards that's how it works with me anyway :)

You can Will a rock to walk all you want but it won't move unless you give it legs! And that's Will in a nutshell!
