Let me say that I might be one of those people who refer to, and I believe I share nicgnostic's feelings. I just started up here a few days ago, but it's clear that most people here have had the experience of coming to find analogs nasty. A minority of us clearly never go through that transition (I can't know for sure I never will, but it hasn't happened yet).
I still find analogs amazing, and that's probably because of some tic in the way the psychology of smoking was developed in me. No matter what, there will always be that part of my brain that associates ciggies with many of the best years of my life, and all of the things nicgnostic mentioned. No doubt all of that "nostalgia," like people often feel for lost youth in general, is part of what floods back when I have a ciggy and gives me that amazing feeling.
I don't think nicgnostic was saying she (?) is on the fence about quitting as a practical matter. I think the point was just to note the nostalgia. I feel it big time, and I probably always will, as it's often said reformed alcoholics do, or former "hard" drug addicts (thankfully I don't know about that first-hand). It's actually a testament to how miraculous ecigs are that so few people here actually feel that. I would have hypothesized much much more of it. My guess is that my hypothesis turns out to be wrong because ecigs are not the same as just "quitting a drug." Rather, they are a surrogate that preserves the essence of the drug, while also being different enough to constitute a separate habit - as we say, not just "e smoking," but VAPING; not a surrogate, but a competitor.
That is truly astonishing. But to return to your question, caligirl, I suspect the answer (extrapolating from my own case) is simply that some people, evidently a minority, never really make the psychological transition to experiencing vaping as a separate activity from smoking. Perhaps we will eventually, of course; maybe it just takes a lot longer for the transition to occur in such people. For my part, I don't really care. I can deal with nostalgia and feeling that ciggies are superior to ecigs without being tempted to go back - the prospect of an ugly, painful death is a more than sufficient deterrent, and a more than sufficient incentive to stick with this surrogate.
Just spitballin'.
