Congratulations on your succesful vaping journey!
Myself, I started vaping around 4 years ago when my (then-new) girlfriend bought me a cigalike which she had a Groupon voucher for, at around £20 - that kind of worked for me, and I cut down to about 2-3 smokes a day (from around 15-20 medium-thick roll-ups with filters per day).
Around 2 weeks later, happy that I was getting along with my cigalike, she bought me the 'Advanced Kit' from the same company for another £20, which turned out to be a fixed-voltage eGo battery and a CE4 tank - from getting that kit onwards, I stopped smoking completely and vaped exclusively.
The funny thing was - I wasn't even really trying to quit - it just annoyed my GF that I made her wait all the time before getting in the car when I 'had' to have my little smoke, and that I stunk of ashtrays.
I went through a range of devices & tanks, from VV eGos, EVODs, Protanks, Aerotanks etc., and eventually ended up where I am now, using my favourite mod - an SXK Zero Mini 60W and the tanks which I ended up using as my all day vapes - I found out that I'm a flavour-chaser, MTL-type vaper, and I like Kayfun-type tanks, my favourite of which is the Taifun GT2.
I seemed to have fell in the middle as well. The Taifun GTII is my favorite single coil tank, but I seem to like the dual coil Goblin series. .7 ohms (two 1.4 ohm coils), high VG blend (I DIY my juice), running around 30 watts. I have about 4 GTII clones from Fasttech, but I have seemed to be using the Goblins exclusively now. I have a few Griffin clones that are a good backup, but because of the size, the Goblins are my all day vape.
Your story reminds me exactly of what I went through. I never set out to quit.. it just... happened.
When I smoked, I made a rule not to smoke inside, or in any car but my own (remember sticky computer?). When we bought a new car, I vowed not to smoke in ANY car. I would wait outside the car while my wife waited for me. I would smoke out on the back deck... looking at the spiders spin a web on the back porch. When I was out and about, I had a
portable ash tray that kept the smell away pretty good. I bought a
cigalike at a gas store for $20US just to see what it would be like... figured I could vape indoors, smoke outdoors. Luckily, I kind of liked the flavor even though it was totally different. It never did get me to quit, but it helped. After buying refill cartrige after refill cartrige, I wondered if there was a cheaper way to do it. I ended up refilling many of those cartriges with some Jhonson Creek french vanilla, and that would extend the life of the cartriges about 3x..but was still throwing many away. So, when I found out there was a way to just refill via the atomizer (stardust/CE3), I bought an $80 ego kit (two 900MaH EGO batteries, 10 CE3's, and 5 juice bottles...
something similar to this)... That's when I really started to quit. learned to rebuild the CE3's, and things got much cheaper.. Went from CE3's to CE5's, then to an AGA-T2(genesis style)/Vamo V3... that got me to fully quit. from there, many mods, many atomizers.. right now, my current setup is an Eleaf Aster 75wTC with a goblin mini on top. IF I could improve on anything, it'd be putting a standard drip tip on the goblin mini. The adapter is too loose, and the newer versions of the goblin leak when you refill it. So, I still prefer bottom fill goblin mini with the glass drip tip.
Anyways, just thought I'd share my experience.
