I smoked cigarettes for nearly 45 years and 4 months ago began using electronic personal vaporizer. I have used mostly simple electronic cigarettes, with 1.8% nicotine e-liquid. Generally, I use about 2 ml of liquid a day. Since the first week, I have had only 3 analog cigarettes, actually, 2 and a half since I did not like the last one and put it out half way through. Previously, I have tried nicotine gum several times, a 6-month course of zyban, and a full course of Chantix. None of those helped, although the Chantix caused me to reduce my smoking a little. However, I continued to smoke through all of those attempts. I have found that the electronic systems fully weaned me away from smoking.
