Good stuff Mac. I too quit on my first tank!!! But alas I have to refill my tank daily as I huff and puff all day long hehe. I cant believe how bad my truck cab smells from all the smoking in it. I jumped in it during the afternoon after lunch and phew it smells like old urine from all the smoke!!! I guess after my morning smoke I was dulled to the smell and just kept adding to it whale i would drive and smoke... YUCK... so tomorrow its time to shampoo the carpets and use the ash tray for a nice scent holster. I am also looking forward to smelling nice all day. LOL my wife tells me I taste like fruit now
But now she tastes like an ash tray 8-o But thats OK i love her and will hopefully make a vapor-er of her too

I have a plan to take her on a date to all the vape lounges and have her try the flavors and see what her preference is. any hoo cheers to you mate I'm glad we have some stuff in common and I am glad to hear of your success, Keep on puffin strong.... do they make a bigger tank?
Aw, that lingering smell drives me crazy, too! Don't forget to wash down the inside of your windows, too. I've got to do that myself soon, and I'm not looking forward to seeing the film I'm sure I left from smoking.

I would definitely recommend trying the febreeze air fresheners they make for in the car (I'm not sure what they're called, but they clip onto your air vents so that they really get blown around in your car.)
And bravo for trying to get your wife to make the switch, too!

It might help her initially if she starts with a smaller, more cigarette-shaped setup (maybe a Nautilus mini tank on a smaller ego battery?) For me, I felt like the bigger tanks and bigger boxed-shaped mods would look silly in a girl's hand if I was using them outside, and I wanted it to "feel" as close to smoking as possible when I started. I wouldn't recommend telling her that she tastes like an ash tray (even though she does, lol!)
Maybe you could help tempt her into switching by pointing out that vaping won't stain her teeth and nails yellow like smoking does. Both that, and hating the smell of cigarettes even when I was still smoking, were the vain reasons I looked into vaping.

And not having to go outside to smoke anymore was another (although that's only relevant for her if she currently has to smoke outside.)
I know the 5ml Nautilus is currently the biggest Nautilus version they currently make (the mini version holds 2ml), but I'm sure there are different types of tanks out there that are even bigger. There are almost too many options, IMO!
I was so happy with the Nautilus that I'm sticking with this mini one (and the bigger version eventually) for now. But definitely let us know if you find a bigger tank that you're happy with so I can check that out.
Take care.
