35+ year 1.5 to 2 pack a day smoker NO LONGER

I started smoking over 35 years ago and have tried different methods of quitting. None of which worked for me. My roommate, who would smoke only occasionally, got me to try V2 ecigs. after trying them for about a month, i was finally free of tobacco cigarettes. My health has improoved tremendously. I can go for longer walks without stopping to rest. my clothes do not smell like an ashtray anymore. And most importantly as of now i have absolutely no desire to ever pick up a real cigarette again.
