Interesting range of experiences!
My husband and I tried disposable e-cigs while on vacation last year. We were staying with family who didn't smoke and wouldn't allow smoking in the house, and it was cold outside. We'd been wanting to try e-cigs anyway, so it seemed like a good time to do so. We weren't really sure if we'd really like them or not, but when we got home from vacation, my husband ordered one 510 starter set and began using it in the evenings instead of smoking. Two weeks later, we were both convinced it was worth it to switch completely for the health benefits alone, and we ordered another starter set for me.
Mine arrived on a day when I was running out of smokes, so I finished that pack, fired up the 510, and never looked back. There was a couple of days of fumbling with getting used to it, but I didn't experience any cravings for a real smoke or any of the negative effects I'd seen all the times I tried to quit smoking before, so I was happy. That was way back in October, and I'm pleased to say, I haven't lit up an analog since the day I picked up the 510, and ... I feel so much better these days!
We're both convinced these things have saved our lives. My husband was a two pack (or more) a day smoker, and my life was getting more stressful and I was working my way up to those levels. We were both starting to feel it in the lungs after decades of smoking, and since we aren't spring chickens anymore, concerns about dying prematurely or having to deal with emphysema for the rest of our lives was beginning to be a worry. But no more hacking, wheezing, or getting out of breath around here anymore! Seriously, e-cigs saved our lives. I am so glad they were invented. LOL!
Also, the bank balance is much happier too, because wow, vaping is much cheaper than smoking!
