Primarily it gave me something to do when I was nervous, worked up or indecisive. That is the way I see it in hindsight. It was also a good way to meet and chat up with people I would not interact with at work. I quit it one fine day four-five years back and haven't gone back to it. I have tried to smoke in a couple of occasions, but I just hated the taste in my mouth. At that point it felt like I had indeed kicked the habit.
