I smoked tobacco for 10 years, up to 30+ a day at times. I tried nicotine gum, inhalers, and the patch. I also tried Champix. I was never able to abstain from tobacco for more than a couple of days, until I tried an electronic cigarette. I have been completely tobacco-free for over 20 months now, and continue to use my e-cig instead of smoking. I have noticed significant improvements in my breathing, sleep, energy, and sense of taste and smell. During the first week of use, i did have a dry throat and a quitters cold but since then I have not experienced any side-effects. I have no cravings or desire whatsoever for tobacco, and am completely confident that, a long as I have my e-cig, I will never smoke again. I have introduced friends and family to e-cigs and have seen 30, 40, even 50 year habits broken with ease. There is no doubt in my mind that I have significantly reduced the harm I was doing to myself and those around me, and that electronic cigarettes should be regarded as the most promising tobacco harm reduction method the world has ever seen!
