Hi tizwas,
You can do this. I've smoked intermittently since I was a teenager (63 now) and this is my 4th (and last) quit. This time was 10+ years inhaling all that crap. Smoking is two habits, physical and physiological. The physical is nothing more than having something to do with your hands; it's the nervous habit. The physiological is nicotine dependence. eCigs satisfy both of those for me.
Quitting is a head game you play with yourself. The first hurdle is physical. If you feel the need for a physical cigarette; start with that. That's where I was. I enjoyed smoking, just not the thought of all the nasty things I was doing to my body. My first eCig was Green Smoke. It looks like a cigarette, it feels like a cigarette, and it smokes like a cigarette. It comes in a lot of different flavors, some good, some not so. I discovered later there were cheaper, almost identical generic versions of the same thing you can get preloaded with flavors or blank cartos you can load with your liquid of choice.
This time wasn't even like quitting. I initiated it because I wanted out of the tobacco world and for me at least this was more like parking my car and riding the train. You just exchange one vehicle for another. I got my GSs July 6th, smoked 5 more reals up to the 11th, and haven't touched one since. You can do the same.
I'm now on a cruise. I found a few flavors and hardware I liked: Backwoods Brew Malty Toffee and eVo Black Diamond among others for flavors, the Vision Spinner to start with and now my Vamo V2 (which is amazing, at least in my limited experience) for hardware. Another way to look at this ... I was a pack a day smoker, in the US that's a $150 a month habit. I now have the hardware I 'need' to proceed, anything else is fluff. I'll recoup my investment in about three weeks, everything beyond that is money in my pocket.
The nicotine dependence is a no brainer. Use whatever level works for you to change the physical habit, then taper off, or don't. The important thing is to stop pumping your system full of the poisonous crap fousted on us by a bunch of money hungry tobacco people. We now have an alternative. It's our choice, not theirs.
Bottom line, if you want out, get out. You've found the path just follow it. You're in the right place. It's my observance that the majority of people here are just like us. They've made it and so can we, and you won't find a more supportive group. Take whichever fork appeals to you and never look back.
