Chain vaper here too. I keep telling myself 'its because it's new' since I've only been at it a few weeks, but the truth is, the juices I have are really yummy and I never get tired of them. I vape all day long, even at work at my desk. Like others, when I can't I don't crave it like analogs.
That is why I found out early starter kits with filled cartomizers weren't going to work. I have a tank system now, and have a 22mm tank going with my favorite juice all the time.
Even with chain vaping, I don't go to bed at night with a tight chest or wake up with morning cough like I did with cigs.
Beckyblue: Yes it does. I was 1-1/2 pack a day smoker, started with 24mg nic level. Still had a cig once in awhile the first week or so, but am finding it easier not to as I go along.
