I'll tell you what I did. Smoking about a pack a day for 20 years. Tried to quit multiple times, gum, Chantix, the other older pill, patches, cold turkey. I always went back. I discovered ecigs, like Blu, a few years ago, but hated them. Discovering PV's, liked them a little more, but didn't want to stop smoking. I went to a vape shop, tried a few mods, and bought one I really liked. THEN, I got e-juice that I wanted and tasted awesome. When you find those few you REALLY like, a cigarette does not compare. I ran out of smokes one day, and made excuses why not to go get some. Yes temptation still hits. When it does, I vape. I think I'm doing really well, and have dialed my mg usage back from 24 to 16mg, and it's fine.
Let your self run out of smokes after you find those few flavors you absolutely love. If you decide to try and have a smoke a few days later, you'll realize you don't want/need it. I did.
