Irasshaimase!
I smoked for 30 years and quit the day I started vaping. Never tried the gum because I don't like chewing gum, but the patch was only good for keeping me from biting my nurses when I was hospitalized. As soon as I got out of the hospital I got some more hoping to quit, but they were so annoying that I was smoking again within a couple weeks. Vaping saved my life *and* my teeth, and not smelling of cigarettes has bolstered my self-esteem. I can breathe better and walk farther than I've been able to in many years.
I chain-vaped like crazy, too, at first. I attribute that to not starting at a high enough nic level, but it could have just been nervousness over letting go of the smokes. Vaping doesn't deliver nicotine to your system nearly as fast as cigarettes, but I found the higher nic levels didn't taste good to me, so I started at 12mg and have comfortably stayed at that level for nearly 6 months.
Vape on!
