Works for me. Still can't kick nicotine, but sure is nice to vape sneakily in places you definitely couldn't smoke.
Also, cheaper.
Can't make any recommendation other than time how long it takes you to have a smoke. When you start e-cig/vape try keep it to the same time/routine to start with.
You need to be just as mentally prepared but not having the withdrawl helps.
In short, I highly recommend…
