Personally, I didn't want to give up nicotine. I just wanted to give up cigarettes.
So that's what I did. I took my carton money for the month and invested in a proper setup after doing my research. I spent time trying different juices until I found one I could use all day, every day.
That was 2 years ago. Everyone around me still smokes, but I've never even been tempted to go back. I smoked for 10 years as well.
