i agree finding the right flavors can be a good calorie free treatI vape because i'm a long time smoker of cigarettes(dislike the word analog, as it is incorrect in the context.) I like the habit and don't want to give it up. Plus all the flavors make for a calorie-free desert!
I never really smoked. I was always a casual, drinking smoker. My gf smoked though. We stopped for a while and were just drinking smokers, but every once in a while she would slip up and buy some etc. She has a friend who is totally into ecigs so I started from there. I have been working my way up and it's way better than those disgusting cancer sticks. Now they just taste like I'm sucking on a dirt tube.
