Hey Joe,
I am not a zero-nic vaper, but I thought I'd address this from how I look at things.
I do have the eventual goal to get down to zero nic. And given that I'm not killing myself with my addiction anymore, I have the luxury of taking my time with it, and doing it at a comfortable rate.
The question is, once I've done so, will I still have my e-cig around?
And the answer to that, in my mind, is simple.
Yes. I will always have an e-cig around. And I will always have a bottle of zero-nic, and a bottle with nicotine. Here's why.
The compulsive habit is HUGE to me. I am probably as addicted to the smoking habit as I am to nicotine itself. I have a compulsive personality, as well as a chemically addictive personality.
I would like to get to the point where if I forget it at home, I'm ok with that. And I think someday I will.
But in moments of stress, as we all know, the reality of addiction makes itself known. I will ALWAYS be an addict.
And in moments of weakness, I would rather have an e-cig I can grab, than get desperate and wind up buying a pack of cigarettes. Lots of people quit for years... and then get hit with major stress, and wind up smoking again. I don't want to be one of them. And I will take measures to prevent that from ever happening, by always having an e-cig.
I would rather make peace with being an addict, and always have that option open to me in a non-harmful way, than try to pretend I can stop being an addict and put myself in a situation where I have no safety net.
When I am stressed, I will always go back to my compulsive habit. And when I am VERY stressed, I will go back to nicotine. The question is simply whether I satisfy that in a way that is harmful, or a way that is not harmful.
I hope to someday get to the point where I'm not hittin' my e-cig all day long, like I do now. If I don't, I'm ok with that. But if I do, I will always have a box somewhere with an e-cig and some juice in it.
As far as nic vs. zero-nic in terms of throat hit... well, the nicotine is what gives you most of the throat hit. So most of the flavors you vape now, in zero-nic, would have no throat hit.
Zero-nic vapers remedy this to some extent by using different flavors - such as cinnamon - which have a punch of their own, even without nicotine. Or, some mix a small amount of pure grain alcohol (PGA) into their juices. Or, they go up to a 5v e-cig.
