1) VaporFi does a pretty good approximation of a Camel cigarette.
2) I definitely no longer enjoy smoking.
3) I believe this will work quite well as a stopgap when I get depressed again. If anything, it will remind me that I hate smoking without me inhaling any actual smoke.
So yeah, glad I bought it, and it will be useful in the future, but… ick. Definitely not taking it up as a habit.
