I was a one pack (20 cigarettes) a day smoker for 23 years. I had previously tried Chantix, but had to stop immediately as they made me shaky, dizzy, nervous and agitated. I was able to quit for 1.5 years using Nicoderm patches. I smoked about 2 years after that and tried again to quit using Nicoderm unsuccessfully after the 3 month treatment. I finally quit for good using a Joye 510 rechargeable electronic cigarette kit and was able to completely stop smoking within 2 days. I knew I was going to be able to quit smoking the very first time I used it. I used 24mg/ml strength nicotine for about 1 week, then went down to 18mg, 12mg and less in about 3 months. I have not smoked cigarettes at all for 2 years now and have much more energy and stamina. My sense of smell and taste has returned. I can’t stand the smell of burning tobacco now. My wallet also thanks me, as cigarettes are much more expensive than e-liquids. I now use a mechanical electronic cigarette (Puresmoker Prodigy V3.1) with a rebuildable atomizer and 6-12mg/ml nicotine e-liquid which I mix myself and save money by doing so. I could quit the nicotine altogether, if I wanted to, but I enjoy it, the same as I enjoy the caffeine in my coffee.
