I pretty new still, but will chime in with my two cents. When I first made the decision to vape instead of smoke, that's what I did - vape instead of smoke. The first few days I was so terrified that I would have an irresistible craving for a cigarette, that I kept my ego in my hand practically all day, or at least within hand's reach.
Know what? It worked. I kept vaping, and waiting for that urge to come, and it never did. So I continued to vape and relaxed a little, since I knew for sure it was working.
It's been almost two months, and I'm now more comfortable about the whole thing. I was making a quick trip to the convenience store for milk and realized I left my ego on the kitchen table. Panic? Nope. I told myself how many times I had driven to that same store and back, (it's close) without a cigarette. Successful trip, milk bought, no craving.
The more I vape, the more I am relating to myself as a non-smoker now. Keep vaping. It will work for you.
PS I started with 18 mg nicotine and it was just barely okay. I smoked 2 packs a day for a long, long time. I went up to 24 mg. and it is just right for now.
