When I quit smoking, it wasn't a planned thing. I had a bad cold and I was miserable (and smoking, of course) and I had an ecig that I'd been sort of playing around with for a few months. So one evening, while coughing and blowing my nose, I thought, what the heck, why don't I just give the ecig an honest try and see how long I can go without smoking? The idea that I'd actually quit right then and there wasn't even in the realm of possibilities in my mind. I figured I might just be able to not smoke for a few hours by using the ecig.
Eight hours went by and I hadn't smoked. Then I made it 24 hours. Then I realized I was actually quitting smoking. It wasn't magical and easy for me, but it also wasn't that hard. Basically, it was easy to not smoke because the ecig was giving me nicotine and it mimicked the physical act of smoking pretty well. The hard part was detoxing from all the other stuff in cigarettes that your body comes to rely on. How that hits you is different for everyone. If you start feeling all weird and out of sorts, keep your eye on the two week mark. Things start to get better by then.
Don't think of it as a forever, don't-look-back kind of thing. It's an hour-by-hour, day-by-day thing. The longer you go without a cigarette, the more empowered and determined you'll feel. Oh and don't drink for two weeks if that triggers you wanting a cigarette.
