Hi prakash, is not easy and it has not been fast for me, the start will surely be slow, in the beginning when i bought my first vape i was still smoking 5 cig per day, then time after time you low you number of cig till when you'll say stop, i'm done.
The best tips that i can give you is to buy a starter kit with some very good tobacco's liquid and after take a very good vape to enjoy the moment of vape like with a cigarette.
In the next days i'll publish which hare for me the best starter kit and vape, follow me and i guarantee that you'll stop smoking!
