I haven't taken a smoke break since I started vaping in April. I vape at my desk and I'm the receptionist. LOL My superiors know that I vape but they've yet to see any evidence in the air. I know they don't care as long as I'm discreet. When I need to really get a vape on, I just go to the ladies room and go at it. Otherwise, I just puff at my desk when no one is around and if I suspect that someone might be coming around the corner, I just exhale under my desk while acting like I dropped something. It's really quite easy to do because there's no smell and the vapor disappears quickly. I get a better nic fix at work now than I did when I smoked.
