For me, I had dual use of both Vaping and Analogs for 3 and a half months before I gave up analogs completely. The more I vaped, the more the analogs tasted like crap. It was a slow process but it paid off in the end. I was a 1 and a hlf a pack a day smoker for 28 years. I had started out with 18 mg nic and found out that it did not satisfy my nic craving. I bumped it up to 24 mg and that did the trick. I used it with a 1.8 ohm coil tank because that makes a huge difference. If you use a higher powered device coupled with a lower resistant coil, you would need to lower the nic for sure. Your body will let you know when you get too much nicotine. As for now, don't count the cigs you smoke, count the ones that you don't. Good luck and anymore questions or concerns, do not hesitate to ask.
