I found after a few hours of
vaping I didn't really like the smell/taste of cigarette smoke. I didn't smoke anything on day 2, day 3 I had a flavored cig (that wasn't bad), and I had 2 cigarettes this morning (darned short lived battery!) and they were pretty gross (I'm on day 4.)
We're all different, I've been smoking just this side of 20 years and I could quit with proper incentive but always returned to smoking the moment that incentive was removed. Maybe you aren't enjoying your vape as much as your mom enjoys hers.
I fiddled with my PV and tried different draws on it until I found the sweet spot where I seem to get the best possible experience without getting nic juice in my mouth or choking on the vapor. If I didn't like vaping, I'd still be smoking-- willpower has nothing to do with it, its easy to not smoke when you like the alternative (vaping) more.
