I had the same problem. I realized that I needed to up the nicotine level in the juices I was buying. I started with 12mg, then to 16, then found 18 did the trick. Only been 5 days but my only "urge" is out of habit. So I have kept my routines but instead of smoking, I vape. The habit of lighting up can be overwhelming at times, so keep your willpower muscle in shape!! After a week, I hardly notice it anymore. Good Luck!!
