When I first quit, July 17, 2007, I used Chantix. Very bad side effects, but I took the whole course (if I pay for something, I USE it up). Nothing really changed with my smoking desires while using Chantix, but I didn't smoke. Willpower, I guess.
Still, during the day, I went crazy. I ate Coffee Nips all day and then started non-stop with Ariva and Stonewall (I still chain Stonewall!). Went to snus as I had done the year before when I was off cigs for 85 days. Then started buying pipes off E-Bay. I smoked a pipe during smoke breaks with fellow workers.
In January, I bought an e-pipe, then the e-cigar, then several e-cigs. I was allowed to vape at my desk. Only the non-smokers in the office gave a damn. They hated me vaping.
The answer to your question is "no" I haven't been off all nicotine but e-devices. But you might have a point. I've read that any smoking rekindles the nicotine receptors in the brain and they start demanding nicotine through cravings. So even though I don't inhale the pipe or cigar, I might have stirred up my hard-wired nicotine receptors.
Right now, I'm dependent on my Kissbox, Java Stonewall and pipe. I think I'll try to wean off snus, since I'm not sure of the impact on oral health.
Even with all this (and I do enjoy the variety), I think of tobacco cigarettes much of every day. I miss them. I don't miss the cough, etc., but I miss them nonetheless. I have, however, made it through numerous stressful situations in the past 16 months, so I know I can stay off if I really want to.
I think I understand what you're saying, but I lack the courage at this time to boot the pipe, Stonewall and infrequent cigar. I do know they add a dimension missing with my e-smoking.
