I just started a week ago, and quit smoking, with a ego starter kit. Believe me, I haven't craved at all.
I was lucky enough to have found a actual store I could go to, and buy what I needed. Actually, they were able to explain what I needed, because it's really confusing at first. Perhaps try to see if there is a store in your region, because the immense amount of information on the internet is quite daunting.
One last point. I was worried that the $50 price for my starter kits seemed like a lot, but I basically made my money back in 7 days, from money saved through not buying cigarettes. And now I just need to keep the e-liquid handy, which is way cheaper than smoking. If you find that you are in it for the long haul, you've have to buy replacement parts, and backup batteries, etc. but after a week and a half, I'm convinced that its going to be much much cheaper in the long haul.
Good luck, and I hope you try it out, and find the experience as wonderful as me. BTW, I've only tried one flavour, RY4, and really like it! I've only tried one, so, not sure how much that recommendation is worth? Cheers.
