I'm just a lucky exception - I wasn't trying to quit cigarettes.
Bought a disposable to get me through a forced couple days in a no-smoking facility.
Figured, "that's not too bad, let me try something that might taste better," and ordered a 510 starter kit (wanted something ciglike and super-portable - I still use em while driving about). Within a week, I found that I wanted to vape rather than smoke - cigs just tasted nasty in comparison, so I stopped smoking. Just like that, after 30 years.
I spend hours every weekend in a RIDICULOUSLY smoky place - and have found no "urge" to burn tobacco.
Rather, I am on a quest to find a perfect every-day vape, and may be doomed to continually fiddle with new gizmos.
I haven't tried to cut back nicotine - maybe one day, but then again, maybe not. See, I just switched to vaping because I PREFERRED IT, not as a way to kick a cig habit!
