I've quit the real smokes since the beginning of the year -- and that feels great! But my goal is to get to 0 mg nic vaping... and then maybe step down vaping a bit. Ideally, I'd just like to have my pv on hand to satisfy that hand-mouth-inhale nervous muscle memory + neural pathway thing that I've had going on for 30+ years -- when I need it.
I've quit cigarettes before: 3 months, 6 months, 9 months. How did I start smoking again after 9 months of not smoking? aaargh. Well. For me, I could never get over the addiction of having the thing in my hand, the physical motions of picking it up, lighting, puffing, handling it. Even when I was really detoxed and long, long over the supposedly more compelling physically addictive part of the nicotine (&tc), I was never over my addiction to the ritual aspects of smoking.
I've gone from smoking 2 packs a day directly to 12 mg vaping, and now 9, and next 6, and then, I hope, 0 or very close to it over the next year, because I have a fast heart rate and want to eliminate or very severely curtail the nicotine. I think the only way I can do that is to have the comfort of the physical item in my hand and the "smoking"/vaping process whenever I need it. So, I don't think I'll ever quit vaping unless some compelling health news forces me to, though once I get to 0 mg nicotine comfortably, I'll try to reduce the vaping to "occasional" during the day.
