Just a quick note...
I am a 30+ year, 2PAD, ex-smoker. My quit date was 08/05/13, and I never promised anyone (or myself) that I'd quit~! My only promise was that I would 'vape' for five minutes before having a smoke. And, I never had another smoke.
Now, to set the record straight, I liked smoking~! I didn't want to quit, in fact I had quit twice before, once for 18 months, and both times I chose to go back to smoking because I missed it.
One thing you need to understand, when you vape, the nicotine doesn't hit you right away like a cig does, hence the five minute rule. Even though not a supported method, vaping has helped uncounted people to quit smoking forever~!
A few simple thoughts?
Don't be quick to lower you NIC.
In the beginning; be sure to carry backups, and take planned extended vaping breaks (until you learn how much is enough to hold you over when you're not allowed to vape)
Find at least one juice you love-this is key (I chose Vanilla variants)
Listen to long-time vapers suggestions for gear-we only want to help you.
My Radius and Kabuki are perfect for *ME*, and *MIGHT* be perfect for you, but only you can decide.
Vaping may not be as *easy* as smoking, but it costs less (unless you collect stuff), is harm reduction for you, and generally, you can vape more places than you can smoke.
