I'm on about 5/6 months now, kinda lost track after the first couple months. You should take note of all those times that you automatically light up. Then look at ways of avoiding or being aware that you are in that situation. Like I drive a lot so I light up as soon as I get out of town. Since I was aware of that, I knew that the psychological and physical urge to light up would be strongest at that time. So I was able to say to myself, I'll be at my destination in 2hours...eventually, it subsides. The one situation that I have not been able to remove those urges is when I drink. But its weird, when I start drinking, its really strong...when I'm legless, there is no urge.
