To quit it is important to change things, rearrange days, create new patterns, and habits. My first work cigarette was lit right after I arrived. Right away, I would light up, and then get on with my day. I needed to change my routines, and find new things.
At the time I had a phone with wifi, and a very good camera (the Kin phone discussed in this post http://tim-thingsastheyare.blogspot.com/2013/04/somber-sort-of-happy-kind-news.html). I installed my work email and my new habit was taking pictures and emailing them to coworkers. Many times I would take a picture of their desk, and send it to them with a question "A little late, this morning?" "It is 7:00 AM, do you know where your coffee cup is?"
It might help to explain that I am normally one of the first to arrive at work (and one of the first to leave, of course). This aids these sorts of things immensely.
One day I pulled my ultimate email prank.
And hung it like this, using a small art program, "Paint" to add the "X" es to it's eyes, and I added a note saying,
|Even nice monkeys can run into problems.|
You see, quitting is a process, and you have to make sacrifices, but not $5.00.
