I also quit with vaping, but in a roundabout way. I used to smoke, but my wife would not have me smoking indoors, and my office was likewise no smoking, so I was on perhaps 10 cigarettes a day. I switched to vaping, and still couldn't vape in the office, but my wife didn't mind me vaping at home if I restricted it to one room.
Then COVID happened, and I ended up working from home. So... Even though the amount of nicotine I was using in the vape was low, I had nothing stopping me from vaping all the time, which is what I did. I actually began feeling just as bad in terms of lung capacity when vaping as I had when I was smoking, largely because I was vaping pretty much constantly whilst awake.
One day I just had a flash of self control, and. chucked my vape, batteries, coils and all the paraphernalia. That was late 2020, and I haven't vaped or smoked since.
Weirdly, even though I ultimately went cold turkey, I do think switching to vaping from smoking helped me to quit. There was a marked improvement in my lung capacity and ability to smell during that time, and that gave me hope.
