Here is another perspective:
You need to take a hard look at yourself, and decide what kind of person you are, and what works for *you*, because it may not be the same as with everyone else.
For some folks, discipline and "pushing through" works best. For me, it didn't. I resented it. I felt like I was fighting with myself all the time, and it stressed me out, and the more I was stressed, the more I wanted a cig, and the more I hated myself, and on and on. With my first attempt at vaping three years ago, it got so bad that I was smoking more than I ever did, trying to vape at the same time ("trying" because back then the equipment was no-where near as user-friendly as it is now), and falling into a major depression episode.
So the second time around I took a totally different approach. I just focused on enjoying vaping. Getting some toys, finding really good liquids, reading this forum a lot and meeting new people, "window-shopping" at all the cool Internet stores. Watching the reviews on YouTube. Just, basically, immersing myself in the culture of vaping, and really, really learning to "love the vape".
The more I did that, the less time I had to think about smoking. And, for that matter, it's sort of hard to pick up a cig when you have a purple Stardust in your mouth with a really cool purple eGo attached to it, and a totally awesome MOV CCRY4 tickling your taste buds.
You only have one mouth. If it's busy with vaping, it's not being used for smoking.
I almost hate to say it, but I'll be plain here: vaping all the time - and I mean *all* the time - is a good thing in this situation. It's also good to experiment with juices a lot - contrasting tastes, looking for interesting flavors, switching them around, whatever floats your boat, as long as you are enjoying it.
The point here is that you many not really enjoy a cig *less* - but as long as you enjoy your vape *more*, you'll reach for a PV instead of a cig *most of the time*.
And, for the rest of the time, get some WTA liquid. You can get it from Aroma e-liquids.
Let the process happen by focusing on the positive - the enjoyment of vaping, rather than focusing on the negative - quitting the analogs.
Once you are mostly vaping, you can focus on your triggers for the part of the cig habit that remains. The morning cig. The after-dinner cig. The-first-one-after-work cig. Try consciously reaching for your PV when a trigger strikes - and use the WTA juice for that. And see what happens. If you've really grown to enjoy vaping a lot - and you will, trust me, as long as you don't make an enemy out of it by picturing it as something that's forcing you to give up your bestest buddy the cig - you will find that, actually, with most of the chemicals replaced (that's what WTA is for), and with a new habit that you enjoy even more than cigs, giving up that one cig will be easy. And that's all this is about, really - just choosing to vape rather than smoke each time. And, btw, I found that most times, just three to five puffs on a WTA liquid takes care of whatever physical craving there may be. It's surprising but true. One moment you feel like you'll just die without a cig, and the next you are asking yourself: WTF was I *thinking*?..
Because you are not really giving anything up - you are *gaining* something.
Yes, it's a psychological game. And it's gradual, not heroic at all - it's just sort of letting things happen peacefully and happily, rather than getting into a violent battle with yourself. But, hey, I'd rather enjoy myself any day, than suffer. And for certain kinds of people it works great.
I think fighting an addiction can be self-defeating at times. Addiction is an obsession. By trying to quit all at once, and by fighting it, we obsess about obsession, and that may not be helpful for some folks.
Anyways, it works for me. I got to the point where I simply don't have to have a cig. Now, it's entirely my choice, and, being a control freak, and stubborn as sin, that's the key for me. I still have a pack in the house - simply to make sure that I *always* have a choice. In the past month I smoked a cig maybe two or three times. I didn't feel any particular need to pick up another one after that. And that's the greatest contrast: before, when I tried to quit with other nic replacements, if I allowed myself even one cig - forget it, I was back to square one, the cravings would just kill me.
Now I simply don't care. No pressure, no particular expectations, just chugging along happily. If I feel like having a cig, I know I can have it. But I don't *feel* like it - I like vaping a lot more. Cigs are boring, expensive, and they stink up my house, clothing, and dog.
For me this process took about, oh, maybe three months? I am not sure, but about that. Again, I wasn't focusing on counting the days, so I'm honestly not certain.
Best of luck to you. There are many ways to do this, and you'll find the one that works best for you. Vaping is the only method I know of that has a great success rate against smoking, so know that you can do it, whichever method you choose, and know that there is nothing wrong with you, and that even if you do pick up a cigarette again, it's not a failure, just a loop of the road.
I also have a pack here....and have the choice. I suppose I'll throw it out eventually, it's almost 2 years old...so ....
