The trick is to find an e juice flavor that you really like and have charged batteries on you always. I started with the ego T and found the flavor wasn't very impressive for any of the flavors I ordered but I started using a dual coil tank with replaceable cartomizers and that has definitely been the way to go for me. The first couple of days were hard, but I just vapped in all the situations I normally would smoke i.e. driving, after eating etc, and now I have no uncontrollable urges for a cigarette. In fact I smoked one last night around a fire at a party I was at and didn't even finish it. I was curious to see how it would be after not having one for a few weeks and how it would taste to me now that my taste buds are getting better. I wasnt impressed and quickly switched back to vapping my atomic cinnacide at the party. Tastes way better!
Bit of Advise. Focus on the differences you feel vapping and not smoking such as going to bed not smelling like smoke, having a fresh car smell, better wind in lungs, not having smelly fingers, and so on. It is amazing sleeping on a pillow that doesn't smell like smoke and these little positive changes can go along way when you are debating a cig or a vape in those tough craving times.
