That chance to just walk out for a few minutes (or simply just to walk...) was probably the main reason I didn't want to stop smoking when I still worked for companies. I just find it hard solving some problems while sitting at a desk - can't help it. Once I started working from home it was suddenly no longer such a problem to stop smoking. Now when I feel like it I just stand up and walk around the room. No more need for excuses.

I wonder if one of the desks where you can stand would also have helped - I never had the chance to work at one of those.
