I've tried almost every possible way of quitting, including cold turkey and nothing has ever lasted. Not smoking made my depression 1,000 times worse. I've been smoke free for over a year now (using the ecig) and my depression isnt any worse than when I was smoking so I'm very satisfied with it. I spend about $30 a month "vaping" compared to $7.50 a day smoking (pack a day smoker) so it definitely saves money too.
