Hi Robert and congratulations on your 4 days. You should be done with physical withdrawal by now, so the rest is, like you said, a matter of changing habits.
There are two ways to look at this. One is that you don't want to throw yourself into a bunch of situations that remind you of smoking. the other is that maybe you do, since it gives you practice at saying "no." Each time you get through one of those triggering scenarios without smoking, it helps to extinguish that behavioral connection. So another way of looking at a crave is that it is an opportunity to extinguish one more cue.
And a third way of looking at it is to expose yourself to as much as you can handle. If you can still get some enjoyment out of your morning coffee on the patio without a smoke, then do so. If it's driving you nuts, maybe have your coffee inside for a while.
My patio was a big trigger spot for me, since that is where I smoked at home. I ended up using that to my advantage in another way. When I had a craving for a cigarette, I said that I was really craving the opportunity to get outside. So I would take a break from the indoors and go sit outside for about the same time it would have taken me to smoke. I found that it actually relieved tension for me to take the cigarette break without the cigarette.
Glad to see you on the boards. Hope to hear of your progress.
