Good choice on the equipment and you've made the all important first step of putting down the cigarettes. That's most of the battle. There'll be challenges coming up but we all had them and you can beat them too. Vaping is a much better alternative to smoking. If you do run into questions or issues, don't be shy about sharing them. Often times there's an answer out there and there are enough members here that you're likely to find someone who knows it.
A pretty good place to start is to figure out how much nicotine you need. The most important take away is don't be worried about stronger nicotine levels. Nicotine without the carcinogens is a bit worse for you than caffeine. Using too weak an e-liquid or cutting your nicotine too soon is a big cause for Vapers going back to smoking. Once you get that, the next stop on the road is figuring out what your ADV (All Day Vape) is. Much as with cigarettes, there will be one that stands out. Once you've got those two things done, well, it's rinse, lather, repeat.
