Everyone is going to have a different experience when trying to quit smoking. I could never understand how some of my friends were able to quit cold turkey...no gum, no patch, no vaping...they just straight up quit. I just didn't have the will-power or self-control to do it like that. I used the gum, the patch, Chantix. None of them worked for me. I was a 1/2 to 1 pack a day smoker, and then my brother introduced me to vaping last July. He was able to transition quickly, and once he started vaping he didn't have any more urges to smoke..
I, on the other hand, continued to smoke from 4 months while vaping. Within that time frame, I was able to cut down to 3-4 analogs per day. But like a previous poster mentioned, I needed the proper motivation in order to truly quit. Finding the proper PV that suits your need definitely helps, but making the conscious decision to quit is key. What really helped me was to switch my environment. Although I was able to cut down, I would smoke one cig in the morning before work and the rest would be for after work when I would be a happy hour with co-workers/friends. So after my quit date, I didn't go to happy hour for two weeks. That way, the temptation wouldn't be there, and that definitely made the difference for me. After that, being around smokers didn't affect me as much. Yes, smelling the smoke tempted me, and up until now there are still times that I want to smoke. I'm sure that will probably be the case for a long time. The difference now is that I am content with vaping, and it's enough for me not to smoke anymore.
Don't feel bad about not being able to quit right away. Everyone takes it at their own pace. You'll get there soon enough.
