Not sure if it's atypical, but you could try reading "Alan Carr's Easy Way to Stop Smoking" and "The Freedom Model of Addictions". The basic premise of the books is, that if you really want to quit, you will quit easily, and that in order to really want to quit you need to reevaluate the reward value of your habit instead of focusing on the negatives. You smoke because you find it pleasurable. The books guide you to better understand what part of your habit you find pleasurable exactly. Is it the nicotine rush? Or maybe the you like the social aspect of it? After finding out what exactly you find pleasurable about your habit, the books will give you pointers on how to reevaluate if the pleasure you derive from it is really all that great compared to other activities or whether it really solves the problem that you set out to solve with your habit.
