Quit-wise, it was an entirely uneventful day. Which I guess is what you want. An eventful day means cravings and attempts at distraction and more cravings and plenty of anguish. An uneventful day is one where you don't smoke, and you don't really think about it.
I reached this point the last time I properly tried to quit smoking. Suddenly, it becomes easy. You don't want to smoke, so there's no issue. High-fives all round.
But I remember that was only a phase. Sometime later - it could be days, or even weeks later - the cravings will return stronger than ever. And you have to be prepared.
