I guess I'm in the position of being someone who started vaping as a way to not start smoking again. When I was in college, I smoked almost a pack a day. After graduation, my wife and I decided to quit, and I put down the smokes one day and that was the end. Never struggled or anything.
But for me, I always missed the act of smoking. Apparently I didn't need the nicotine, but I craved the relaxation of having a cig. After a lot of research, I decided that I would try vaping. It was that, or buy the occasional pack of smokes. And I know that smoking is awful for me, so the vaping is a much better alternative for me.
I generally vape 0mg nic liquid. I enjoy the flavor and find I don't even need to lung inhale to derive enjoyment. So I vape like I'm smoking a cigar. Get all the flavor and enjoyment, and none of the nastiness of analogs. When I'm having a particularly bad day, I may vape a little 3mg nic juice. It's a treat. And I do it instead of having a drink.
So for me, I'm smoke free, basically have no alcohol and vape instead. I'm happy with that!
