When I first started, I relapsed back to analogs a couple times. The hardest thing about staying with vaping (and I still struggle with this today) is having a variety of liquids. If I vape on only one or two flavors, it gets old fast and I look at an analog with desire. If I have a variety of liquids, then I don't even THINK about analogs.
What I do find interesting though is some ex-smokers and non-smokers' attitudes towards vaping, where they see it as "just a different thing to get hooked on". In fact, I was getting my hair cut and the woman doing my haircut asked me about e-cigs. I told her the basics, about the health, financial, and scent benefits that e-cigs offer. She simply said "yeah, but it's just as bad because you're still hooked". My response was "we are hooked anyway, not just by the nicotine but by the habit. If you do ANYTHING 20 times a day for 17+ years, it's hard to overcome the habit. Might as well switch to a healthier and more affordable alternative". She dropped the subject.
I think some don't understand that it's not just an addiction, it's a character trait after doing something multiple times a day for many years. It's more than a habit. It becomes our personality. For me, not having the nicotine, the smoke (or vapor, in this case), or the object producing/providing/delivering said elements, would be like changing a big part of my life. Smoking was there when other things weren't. It has been [at times] a crutch, or a companion. Being such a big part of my life, I am not yet willing to let it go.
That being said, I believe that the interpenetration of the role that e-cigs play in our lives is extremely subjective. For some, it's just an addiction. For others, it's a way of life.
