Your craving for nicotine doesn't go away just even if you realise you're not trying to recreate the sensation of smoking. In my personal opinion, for some people it's about feeling like your smoking(whilst not) and nicotine stength is less crucial, for others it's about getting some nicotine into their system(to take away the itch) and not so much of the act of sucking on a stick in their hand, others it might be a bit of both. It's always been a bit of both for me, but mostly it's about a replacement experience that feels kinda/almost like smoking, in my early vaping days, 18mg was making me sick but i really need that level of nic to stave off the itch to smoke(i made myself feel crap at times, but kept going all the same). I'm down to 3mg now and could probably get away with not using nic and to be frank, 3mg nic juice isn't likely to be doing much harm(comparatively with smoking if nothing else) and it adds an extra 10ml of juice to my shortfills, thus they last that bit longer.
I tried to get my mum on vaping and started her with 12mg juices, had her test juices i have at 3mg first(to get a feel of what flavours work for her), i wanted to start her at 18mg but she said go lower(we got a mix of 12mg and 6mg). She didn't enjoy the tighter high nic vapes or the high nic juices at all, airer kits with low nic juices work great for her though(things more along the lines of what i vape now some 15-16 months along from quitting). Different strokes, not everyone has the same requirements when it comes to vaping. I've vaped the left over 12mg / 6mg juices and she's happy having the odd toot on 3mg juices we sorted out for her later, it's enough for her (comparatively i'd never have managed starting out that low).
Welcome, and well done on quitting smoking. As you can see, during the festive season, some of the inmates get a bit carried away and excitable, and most likely pissed. It's not normally quite so errr ... hmmm.
