I smoked cigarettes for over 20 years, a pack and a half a day. I have had quite a few failed attempts to give up smoking in that time. Prescribed medications (Wellbutrin) where I went back to smoking after the course of medication ended. Dummy devices like clove (and you think cigarettes stink!). Nicotine replacements. Cold turkey. All unsatisfying and ditched within 6 weeks at most. I now have a young son and decided I needed to quit and had to make it stick. I spent 2 weeks investigating e-cigs online, reading reviews and health studies. 16 weeks ago I used my e-cig for the first time. It was also the last day I had a real cigarette. 16 weeks on and I have more energy, no cough, no wheezing, better taste and smell. I cannot believe how easy it was (for me). Thing is I loved nicotine, it had great benefits to my concentration and focus. Switching to ecigs worked. Quitting cigs (and therefore nicotine) never did. Oddly, the need for nicotine is a lot less now, I never think of popping out in the middle of a movie for a vape, I always did when I smoked. Which tells me that nicotine is nowhere near as addictive as I was led to believe.
