I've been vaping at 0nic for awhile. Probably not a full year, but getting close to it. I didn't really keep track of when I dropped to zero nic.
If I vape the rest of my life, I'm far better off than before, because I had expected to smoke the rest of my life. I smoked heavy, and prior to vaping, I didn't think I could quit. When I started vaping, I didn't expect it to work. It was just another attempt to quit.
After I'd been off the cigs for awhile, I started cutting down on my nic, a little at a time. I'd take the last of my 24mg, some 18mg, mix them half/half and use that as an "in between" step on my way to 18. Then after a couple of months, I'd do it again, mixing 18 with 12. When I started going under 6mg, I vaped at 3mg for a long time. I was very nervous about the idea of 0nic. I'd been using nicotine for most of my life. The guy at the local vape shop told me "If you're at 3mg, you can go to 0, you won't notice. You're barely getting any nic as it is". So I tried it, and he was right.
When I went to 0, I thought I'd vape without nic for a bit, and that once I was used to not having nic, it would be easy to just set the thing aside. After all, at that point, I'm done with the addiction, right? Well, I'm not addicted to nic, and I don't get the jitters and such if I don't vape, but the habit is still very strong. I'm still much happier if I can vape. The same triggers that used to make me want a cig (like right after a meal, or if I go out drinking) still make me want to vape.
Most of the reasons I had to quit cigarettes don't apply to vaping. It doesn't have the same health implications, it doesn't smell so bad, and I can vape in a lot of places I wouldn't be able to smoke.
But there are a couple of things that make me think it would be nice to quit.
Cost, for one. Vaping is much, much cheaper for me than smoking was. Even so, I have a Provari, an MVP2, a lavatube, a buzz pro, a bunch of ego types, etc. And I buy juice and coils for my protanks. Something new is always coming out, and I'm always being tempted. It would be nice to save the money.
And it would be nice to not have the habit. To not have to remember to bring my PV, or extra batteries, extra juice.
Ideally, I think I'd like to be able to vape on occassion, but not do it most of the time. However, I think that if I tried that, nothing would change. If I want to quit, I'll just have to quit.
I think about this a fair amount. I haven't made a real attempt to quit vaping so far. The longest I went was 24 hours due to some dental work. I made it through that OK, but I wasn't happy about it. Of course, after a bunch of dental work, I doubt anything was going to make me happy.
I have a river trip (tubes and canoes) planned in August. I may decide, at least the first day, to take no PV with me on the water, and see how that goes. If it's not too bad, that may encourage me to really try and quit.
