Don't be so quick to cut down on the nic! Especially if you are still having cravings. I used 36 mg juice for the first three months that I vaped. That is what it took to get me off the cigs.
You may surprise yourself if you do break down and smoke. The cig will most likely not taste as good as you remember. If the 36 mg does not help, some people are having good results with WTA. Whole tobacco alkoloids. So, that may be another option.
You may eventually need to get a bigger PV. I went to Variable Voltage after 3 months of vaping and it made all of the difference in the world.
Good luck and don't give up. Even if you do smoke, get right back on your PV. It takes some of us a little longer then others. I was not one of the ones that put the cigs down right away either.
Hang in there.
BTW- I just noticed where you are. There are many of us here from SC and some even very close to you. Be sure to join the South Carolina Forum in the Social Groups section when you get a chance
