For what it's worth,
I am nearing the three month mark on my quit and there was no 2 month crisis, not even a three week crisis... in fact no real crisis to speak of that is related to quitting.
Sure, there have been changes in my life, and situations to deal with, and occasionally someone smoking nearby me and I thought for a second or two that a cigarette would "taste good".
But then I just remember that I can't just have one smoke... It isn't possible. And in fact, I don't want one.
To anyone just starting out, Joel is right, do not be intimidated or influenced by the notion of "terrible 3's" or anything of that sort. Once you are sure in your quit, that has no importance, except that you must always remain vigilant and follow the one, provebial rule... need I repeat it? NTAP!
