I decided on the Innokin VV V3.0 with a mini nautilus. I really super like the square design of that battery, but I don't know if I want the box design just yet. The Nautilus just made sense to me because of the glass. All the more reason I need that square battery. Plus I got one of those fancy new Nature designs and, from what I have read so far, I should probably get more coils? How long will the one coil last? I haven't looked at juice yet either, so what do you guys recommend there for reputation of quality ingredients? Some of the sites I have looked at seem...shady. I would prefer made in the US...maybe a small batch *brewery* type of thing until I have decided to make my own. Any accessories recommended for the set-up?
So happy I didn't ask for Reddit advice! You guys are fantastic! ♡
Lol, I came in fairly late in this conversation. But I think you made a good choice. I firmly believe a variable voltage pen sized battery would be your best option to begin with, and the innokin name is a very reputable one. The only thing I am not wild about with the VV 3.0, is it's aesthetics with a round tank, and most tanks are round. The Nautilus is a good tank as well. Yes, I would get several coils to start off with, but wait until you use the stock one and vape that for a day to see how you like it. Finding the coil/voltage combination is something that might take a while, so if you can, buy a selection of Ohms for your nautilus.
Now as far as the juice goes, this is an entire matter onto itself. I was similar to you when I quit... I had a 20 year habit and I smoked 1 pack/day of doral orange (I think those were "ultra lights"). Ecigarettes didn't totally stop the habit, but it cut down from a pack a day to 2/day... that lasted for about a month or two... then I decided to just see how long I could go without one, and it's since been over a year since I've had a cigarette. The hardest part was finding the right juice, and what I like. At first, I tended to go for the higher PG (propylene glycol) ratios.. for some reason, those gave me more of the physical sensation of smoking... it had more "throat hit". Since then, I've lowered the niccotine content then switched from a more PG to a more VG mixture.
The flavor that did the trick for me, was Hangsen's RY4... it was a tobacco based flavor, but had a very strong caramel flavor to it. Hangsen's been around for a while, and there is no options besides niccotine content. After I was off the stinkies, I migrated to more fruity type flavors and a USA based eliquid company. Mt. Baker Vapor is my juice supplier, and my go to vendor for e-juice. They can custom make the juice for you, they have good customer service, fast shipping, low price, and they're based in the USA (Washington state).
Since youre first quitting, I would go with a higher nicotine level. I believe this will help you for two reasons.. one, is you need to re-train your brain that the nicotine comes from Ecigs and not cigarettes. That little trick I learned about reading up on how Nicotine works. You will have to re-train your brain. Until then, you will still have cravings for regular cigarettes. So, if you feel like you HAVE to have a cigarette.. wait a bit then go ahead and smoke one. Next time that happens, go a little longer before you smoke another. There will be a time where a cigarette doesn't taste good at all, and you can probably quit all together. After vaping a few months, you can then work on lowering the nicotine content.
...the second reason I think a higher nicotine content will benefit you, is you get your nicotine intake rather quickly, and you don't have to waste time vaping. This will allow for stealth "nic fit" sessions to last a lot shorter. But again, once you're on the Ecigs, you can lower your nicotine content. I went from 18mg to 12mg, now I vape 6mg... and just recently, I've been adding VG to my bottles to dilute it even lower.
In either case, welcome to the forum.. I want to hear a lot of questions from you.
