Been using them for eight or nine years, from back in the days when everything was three-piece. Haven't smoked a cigarette since. I still smoke pipes at home, some, but that's not about nicotine. (I'll put down a pipe to take a hit on the e-cig. ) The best part is that I can use one at my desk at work, and in my non-smoking work vehicle. I've even used them on airlines, but I was surreptitious about it. Oh, and I can check into non-smoking motel rooms, and they smell a hell of a lot better! Good for you! Now begins your adventure to find the kit, and the juice, that best suits you. It will take years, most likely, but it's an enjoyable adventure. Hint: don't buy disposables. Get a bunch of batteries and a power-delivery "mod," and a tank or great big cartomizer, and start buying juice in quantity. I'd be happy to share my experiences and suggestions with you if you like, in PMs so that we don't bore everybody.
