The thought of living without
vaping is a little scary, just as scary as the past thoughts of living without smoking. I haven't had an analog since January 24, 2010, and the fear of quitting smoking is long gone. Now, it is a matter of overcoming the fear of quitting vaping. I think quitting vaping will be easier than quitting smoking (although quitting smoking wasn't hard at all thanks to the e-cigarette.)
I don't have to go outside for "vaping breaks" like I did with cigarettes. I can go an entire day without a vape if necessary, hardly a possibility with smoking cigarettes. Things just seem a little more doable with vaping in regard to quitting altogether. Also, relapse is not half as devastating on the e-cigarette. It is far more demoralizing to relapse with cigarettes than with vaping.
If I were to quit vaping (which I plan on doing sometime in the foreseeable future, I would probably buy several bottles of eliquid in varying nic strengths. In my case, start with 18mg, then drop to 12mg when the 18mg bottle is finished, then drop to 8mg when the 12mg bottle is finished, then to 4mg, then to 0mg. Maybe vape 0mg for a month, or at least have it on hand just to ease the oral fixation. That's the plan at least, we'll see. Best of luck to you!
