6 a day is a good result for such a long experience.
About awareness, my friend wrote in his notebook every cigarette he smoked every day while trying to cut down the number. Worked for him, he did it for half of a year and quit.

I wanted to share, I had been smoking since 11, has an enormous addiction, tried a lot of methods, but it was pointless. Nearly at 28 I quit with the help of electronic cigarette, using it instead of common. I feel that I have more energy now, and it helped a lot. I started to draw again and feel healthier since then.
I'm afraid I don't know how to quit vaping, but not inhaling smoke - products of burning - is much better.
