I also agree with the "Flavah 'Ho"

about upping your nic levels while you make the transition to non-smoker. Also, keep in mind that nicotine from vaping is mostly delivered via the soft tissues in your mouth rather than via your lungs from smoking.
And here I will give you the same advice given me by the guy that sold me my first kit and it works, and it is painless.
When you get up in the morning and you really want a stinky, go ahead. Have two if you need to and then go back to vaping.
Every time you just gotta have one, have one while keeping in mind that you want to quit and then go back to vaping.
Before bed, if you just gotta have one, have one.
I know this sounds silly but it works!
Using this method, after about 10 days, it got to the point where I just did not want to light up a stinky as I had gotten to the point where I actually enjoyed vaping more!
And after you have made the transition, you can start to gradually lower your nic level.
