That was exactly how I experienced it, when I was trying to get smoke-free the 2nd time, after my relapse. I kept vaping and vaping, wondering why I was still smoking, with all this vaping going on.

Gradually it occurred to me that the first time around, I actually had made a choice to just not smoke anymore, but it was so subtle, it was hard to remember actually making a choice. So I finally told that 2yr old in my head to SHADDUP ALREADY! harping at me to go smoke, go smoke, because I JUST WASN'T GOING TO DO IT ANYMORE! The 2yr old shaddup.
Then of course, the cravings did come back, after I'd been smoke-free again for 10 days. But I'd made a choice not to smoke, so instead of caving instantly, I got some WTA and tried that. And it worked. Probably because I really needed it to work, and also because in the aftermath of intestinal surgery, my body really needed those other alkaloids -- but I still had to make the choice to get them from something other than cigarettes.
