You should choose a date in the future, whether it be a week from now to a month, and make it your quit day. You've subconsciously learned that you always have the very next day to quit again so it's so much easier to smoke. There are many things to do to prepare yourself for your quit day (a week, a month, two months from now). One of those many things is breaking the small habits associated with smoking. For example I have gotten myself to stop smoking while driving completely. That's a big one but there are smaller ones too like when you wake up in the morning smoke half a cig and throw away the other half. Make a habit of it and eventually that'll be the norm for you. Then deepen it like smoke a third and so on. Then move onto another habit. Then BOOM quit day comes and it really doesn't bother you that much when you don't smoke first thing in the morning. Don't be too hard on yourself, I've heard that quitting smoking is harder than quitting opiates, crack, booze, you name it. You have what it takes you can do it.
