First reaction:
Zero nicotine?! Cartridges of factory flavor?! I coulda never quit with that.
Second reaction:
Three points.
1) You might need one or all three of the following for your ecig satisfaction: higher nicotine, better tasting juice, higher voltage vaporizer. I needed all three to successfully stop craving cigarettes. (Although my brain still didn't like leaving behind the other components of tobacco...see #2).
1a) Look up what people recommend as the better juices (try housemade ones rather than the imported Dekang stuff your carts came with). Buy juice and refill your cartridges instead of buying carts; it's an awful lot more economical and better tasting. Taste, throat hit and vapor make a
huge difference in satisfying the desire for smokes.
1b) You need
some nicotine to make the switch first. You can always taper off later. One way to do it: Try a low nicotine version of a flavor, and if you like it, buy the high nicotine as well, and trying mixing the two until you find satisfaction at the right level.
1c) Then
consider trying 5 volt models like the Prodigy, the Xhaler, the GLV, etc. or 6 volt models like the Chuck, the Super-Six, the Adaptever, the Xhaler again, etc.
2) Nicotine is not the only psychoactive substance in tobacco. There are alkaloids and mild MAOIs that some people really miss when they switch to ecigs. (Others don't have a problem. It seems to be an issue of individual brain chemistry.)
This thread, while dang near epic in length, is one meeting of the minds on this issue, and on some tobacco alkaloid extraction concepts.
There are others in the Nicotine subforum you might find interesting to browse.
2a) If this is the case for you -- nicotine is not enough -- try Swedish snus or dissolvables or snuff. Check out the "Other Alternatives to Smoking" forum. People go to these not just because they're different in taste/usage than ecigs, but specifically
because they have the alkaloids and "X-factors" we're missing in ecigs/pure nicotine. They're still a heck of a lot safer than inhaling all that burned tobacco.
3) You sound like I did for the first couple weeks of vaping in terms of satisfaction (and later in terms of missing the alkaloids' psychoactive properties). Something wasn't clicking. You have to be open to adapting your tactics, though, because all you know right now is that what you've been doing
doesn't work.
My personal formula took research and a few trials but I found it: 12mg instead of 6mg, the Xhaler at 5 volts, Tasty Vapor part-VG (more vapor!) juices, and KR808d-1 cartomizers alternated with 510 atomizers.
Every person on this forum who has quit successfully can tell you their "formula" too. It took some of us longer than others. But it's worth the effort to find your individual solution.
