I love not worrying that I smell like smoke. Smoking is so taboo in my working world, we still don't have the luxury of being able to "vape" in the building. Most of the gang in the outdoor designated smoking area have switched to vaping. It's nice to be able to go back to my work area and not worry about smelling like smoke. Love not having ashes all over my car.
I smoked 2 plus packs per day prior to starting ecigs just 3 weeks ago. My own sense of taste and smell hasn't changed much, yet. I sleep a little more soundly but my sleeping had already improved immensely ever since I had improved my diet, anyway. Other than that, I haven't noticed much change in health or ability, yet. Hope to see a kick in to better performance in a few weeks when it gets cooler here and I start running again. I'm going to start taking the stairs up 4 flights rather than the elevator this week, to see if it seems easier. At least I want to try it, that's some improvement, i guess.
