Was told last December after an unsuccessful surgery to remove a blockage in my left leg to quit smoking or lose my leg. I had smoked 2 packs a day for 40+ years and never really considered quitting until that moment. Over the last year I have gone through the patches, gum, pills, hypnosis, etc. trying to quit smoking to no avail. Best I did was 3 weeks taking some pills they gave me to take. I ordered a starter kit from V2 and tried smoking them for a month and was able to cut down to half a pack a day last September. Last October my son in law introduced me to a Triton tank and battery from Halo and explained I could get any flavor of juice I wanted to put in the tank at a nicotine level that would stop any craving to smoke my (just learned this) analogs. So I order a bunch of different sample packs of different juices from different places. I received one called tobacco hazelnut on the 18th of November and haven't touch anything else since. Even though my wife still smokes I am not bothered or tempted to pick up an analog.
The moral to this long story is that everyone is different. Just need to find something you like
vaping more than smoking and from my experience it gets pretty easy from their.
