Welcome kimster;
Vaping isn't exactily like smoking. Only smoking is like smoking. I sucked down 2 to 2 1/2 packs a day for over 40 years. I had some minor withdrawl at first, but nothing serious.
I first settled on vanilla flavor. I started on 24mg of nic, but I kept a bottle of 36mg for my morning coffee and after dinner. That little spike helped me through the rough times. After about a month, I stopped spiking in the morning and it worked out well.
I feel that it's 50% e-cig, and 50% mental. You have to put your mind to it, and the rest is downhill. I'm a firm beleiver of getting away from the tobacco flavors. Experiment with other flavors, but don't overwelm yourself at first. Find a nice flavor and stick with it for a while. Before you know it, cigarettes will smell and taste gross. Hit a little higher nic if you feel jumpy, but don't over do it.
I'm doing menthol now. (18mg) It's a clean minty taste, and the menthol gives me the throat hit I need.
Hang in there kid. We're all here to help.
