After 45 years of smoking up to 1-1/2 packs of cigarettes a day and at least 8 attempts at quiting, I purchased an electronic cigarette kit 2-1/2 years ago, and except for the first month it took to arrive at a satisfying combination of battery and cartomizer I have not even thought of a real analogue cigarette since. My experience has convinced me that e-cigarettes are the single most or even the only effective tool to quit smoking. I tried patches, Wellbutrin, Nicorette gum, an expensive hypnosis program, and cold-turkey without success. My smoke-free life using conventional cessation methods lasted no more than a month or two before I would be back up to a pack or more a day. As mentioned above, it took about a month to arrive at what I consider a satisfying combination of pieces of equipment. The first kit I purchased was practically useless, producing almost no vapor with a battery that died after just a few minutes of use. After some online research (that I should have done to start with) I arrived at a combination of a high-capacity eGo battery and dual coil low voltage (DCHV) cartomizer that produces lots of vapor and good taste and smell. I have tried many flavors of e-liquid, but enjoy chocolate most with the added benefit that most people seem to like how it smells. While my story is admittedly anecdotal I think that e-cigarettes have, if not saved my life, at least added years to it with the bonuses of no longer making me and my clothing smell terrible and not having to sneak outside to have a smoke in all sorts of weather. In addition, they are on a daily basis much less expensive than smoking and have no dangerous second-hand by-products either in the vapor (one recent study) or in disposed of butts lying around. If I believed in miracles I would say they are miraculous.
