Ok, so maybe I haven’t been to bed yet (at least for the night), but I wanted to post this now while it was still fresh in my mind.
Owing to ‘unforeseen circumstances’ I have to start over with the whole quitting thing. And to think, I had gone almost a month as well. 
But… since I (almost) succeeded once, there is no reason why I can’t do it again.
One thing that occurred to me: Whenever I went out for a cigarette, especially at the dead of night, with a mild, pleasant breeze, just to sit there and think, it always used to provide a moment of clarity, or a random thought, a random memory. If there was ever something on my mind, just to go and sit there, in the peace of the night, everything seemed to become clear. What to do, or to say… of course in the end it may have in fact not turned out to be the right thing, but at least at that moment it seemed right.
