Hi Barbaub. Delaying works for some, but I believe that the technique is to delay some before having a cigarette. I think the idea of delaying as long as you can kind of sets you up to "break" and have a cigarette when you can no longer stand it. In my opinion, using the technique in that way is counter productive. As I understand it delaying is meant to be an encouraging thing, not discouraging or too hard.
I delayed having cigarettes in the last 10 or so days of my prequit. But I never did it to see how long I could go. I used the delay to test feeling OK with not smoking. If something triggered me, I used the delay in order to think about what was triggering me. But I pretty much knew when I would have a cigarette--2, 3, maybe sometimes 4 hours later. During this time, I wasn't really withholding cigarettes so much as trying to get comfortable with not smoking.
You can get this, all pre-quit effort is worth it. You kind of can't really go wrong! Keep up the good work! 🙂
