Well, fwiw, I smoked tobacco for many years, but I quit and haven't smoked for several years. My piece of advice: don't use the nicotine gum--it's as addicting as tobacco and almost as expensive. I would think the same is true for e-cigs.

It's tough to quit and you will continue to crave them for a long time afterwards, but the day will come you won't even think of them anymore--and wonder why you didn't quit earlier.
