Hang in there. Every single quit is different, and I've personally found the mental addiction *never* goes away; the best you can do is to make it go *dormant*. On my longest previous quit (out of dozens), I lasted 9 months, as all that time I felt I was giving something up. The addiction would always be saying, "Why are you going through all this just to deprive yourself? Not only are you miserable, you're a hypocrite: you know you're really a smoker at heart!". I finally became too fatigued with mentally arguing with myself 24/7.
This time I've been smoke-free for 18 months and counting. The difference is that I changed my whole mindset, and decided to adopt a "drill sergeant" attitude towards myself. Traditionally I'd always "babied" myself when I quit (e.g. allowing myself to eat whatever I wanted). This time, I didn't brook ANY excuses. Whenever the argument would start, the "drill sergeant" would pipe up (in the best R. Lee Ermey voice): "Quit your miserable puling, you pathetic piece of ****! You eat that, and you'll be a fat, slobbering b*****d in no time! Then you'll use that as an excuse to start smoking again anyway! What's that, puke? You say you're not really being yourself by quitting? TOO F*****G BAD, YOU WHINING CRYBABY! I don't care who the hell you feel like: yourself, someone else, Robert Johnson, Magic Johnson, whatever... It doesn't matter who you were, this is who you are NOW, so just deal with it, MOTHERF****R!"
Anyway, you get the picture. Seems to have worked so far... shuts the little voice right up. This quit, every single time I've had an urge, I can wait ten seconds, then calmly and truthfully realize that no, having one would actually not be all that great after all, and move on. A nice side-effect is that this attitude helped keep me from gaining weight as well, as the drill sergeant attitude to stick to a strict daily calorie-count. I actually LOST weight this time!
It's all mental. No matter what happens, guard the quit, as the next attempt your mental state will undoubtedly be completely different! Good luck!
