This is what helped me quit a 35 year smoking habit. I had tried using nic gum, patches, prescription drugs, and hypnosis. Nothing worked.
Once I had my vape starter setup, I decided on a quit date. I had one pack of cigarettes and vowed I would never buy another pack. I knew I would have cravings, so I allowed myself four cigarettes a day. When I felt I just had to have a cigarette, I smoked half of one, and put it out to save for the next bad craving.
Those second half cigarettes tasted pretty nasty, but I believe that helped me to quit. When I got a craving for a cig, I vaped more. If that didn't help, I smoked half of a cig. As the week went along, I began to prefer the vape over the cigs. When the last pack was gone, I no longer wanted a cigarette.
If I were you, I'd stop buying your favorite brand of cigarette. If you usually smoke a plain tobacco flavor, buy a menthol. If a menthol, buy an unflavored tobacco. Don't reward yourself for any reason by smoking a cigarette.
Use a nic concentration in your e-liquid that will satisfy your nicotine cravings. Some people have a separate bottle or tank of a higher nic juice for those real bad cravings.
In the end, it's going to come down to your determination to quit for good. Do what you can to make "Vaping Good" and "Smoking Bad".
