From my personal experience with vaping I can assure you that the first thing you must do is to find a e-liquid that suits your needs (taste,throat hit and vape density).
For me it was based on trial and error method.I've tried countless amounts of e-juices with and without nicotine. I too did had cravings for my old analog cigarettes but I managed to avoid them for a couple of days trough vaping and focusing at work and on the fifth day, my body got used to vaping and I didn't mind the smokers around me anymore when I went out with my friends to pubs or night clubs.
The thing that really helped me to stay away from my old habit was whenever I had the desire to light a cigarette I always reminded myself of the negative traits involved with analog smoking, which are undeniably huge.
Just put your mind into it and endure a couple of days without the analogs trough vaping. Good luck!
