I've only been doing this a few days, but here's what I would do...
Get a lot of extra batteries and several extra carts. Get a lot of juice, in small quantities so you can find what you like and your taste will change quickly!
In 5 days, I went from not liking a flavor to it being the only one I like RY4. I thought I would want the cigarette flavors, but I don't like them at all and prefer the sweet, creamy and smooth flavors.
Get some PG and VG, so you can try both. Get various strength liquids.
I have 6 batteries total for my KR808D-1 and use 2 or three a day. Recharging isn't a "PITA" for me and I kind of enjoy all the little rituals (charging, refilling, cleaning).
And most important, at least for me, keep reading the forum. There is not only a wealth of information, but some really smart and hilarious people on here. YouTube video reviews are also nice. Grimm Green and Phee3 are my favorites. You can follow their progressing from starting out to being 'experts' and see how their evolution is going to be a similar path as your own.
Keeping yourself involved is going to help making the switch to ecigs even easier.
