I really don't worry that if I take a single puff that I will return to analogs. Not anymore. A few years before I discovered vaping, I had quit for a month or two. I remembered when I would smoke 3 analogs a day. I thought, "ah, one won't hurt me. Even 3 a day wouldn't be that bad." Unfortunately, those 3/day was 1 PPD before I knew it (and sometimes more).
This time is different. It probably took me 3 weeks or so to quit smoking after I started vaping. But, I would still get a craving for one. Then my friend would come over and she would give me one. So, when she came over (about 1/week), I would bum one. Each visit I was able to smoke less and less. Then it got to the point that within a few drags I would become physically ill - nauseas, headache. I eventually told her that the next time she came over, no matter how much I begged, not to give me one. I was just going to waste it anyway. Now even the faintest whiff of an analog makes me ill. Even the smell from someone coming in who has finished smoking.
I won't say I don't get this nostalgic craving for one (especially when I see it on TV - where I can't smell it), but I know the second I smell it, I remember how ill I felt the last few times I tried to burn one that I have no desire to smoke.Those last 2-3 I tried to burn and got so sick, I couldn't believe I used to smoke 1 PPD (even up to 2 PPD on some occassions). I don't know what made my last quit different (could it be the vaping?), but this time I know I would never go back. It can't be the length of time without because I have quit for longer periods and returned with the greatest of ease. The funny thing is also that when I quit for those 2 months, I did it because I wanted to quit. When I quit this time, I really didn't even care. I entered the world of vaping because my friend wanted to use it as a tool to quit. I just decided to join her for support (and I'm the one that quit and she still smokes - go figure).
While I don't worry anymore, I have been there and do know the feeling about the inability to have even a drag off someone else's. Like an alcoholic that can't have even a sip of alcohol...
