My dad went through the same process. He smoked his e-cigarette essentially non-stop, all day long, everywhere he went. He eventually ditched it and went back to real cigarettes, though he smokes drastically fewer per day now than he used to. Unfortunately, though, I expect his habit to be back in full swing in the next few years.
