I've spent the past 6+ months trying to get away from cigarettes completely. I've been vaping the whole time, but I would still smoke 1, 2, 4, 10 a day depending on circumstances. At most I would make a week, and then have one again.
I vape 24 mg all day, and even have a good amount of 36 mg just in case. Still needed a cigarette.
I got rid of all of my manual batteries, thinking autos would kill that itch. Nope, still needed to smoke but it was less on the autos than on the manuals.
Then I got 3 ml cartomizers, thinking if I had to change them out fewer times throughout the day it would help me bull through it. Nope.
Seemingly overnight, I became a dripper. On a full auto super-mini. Perfect throat hit, great flavor and I get that lung action that you can only get from an auto or a cigarette. Now it's been nearly 3 weeks since my last cigarette. That's the longest I've gone without a smoke since 1999. Possibly I have finally found a way to vape and kill my cravings for a cigarette.
Keep trying. Try different devices, different strengths, different delivery systems. Try everything you can afford until you no longer have that itch. And if it comes back, try something else.
Good luck.
