I myself vape constantly. I realized when I'm working on a problem my vaping is more drug out. But if I'm not doing anything at work, or if I'm doing some trivial or repetitive task I'm constantly vaping. I've got two carts going. One with nic, and one without. If I'm sitting at the computer or reading a book I use the no nic, and put in the nic if I feel a craving. Its working well so far. I know for a fact that this is better than smoking, as I was quite the chain smoker. You know you have a problem when you've had 4 cigs and you still want another :S
