> Nicotine withdrawal seems much less severe after I switched to vaping.

I noticed this too. I was a chain smoker. I became a chain vaper, managing to quit tobacco in the process.

Eventually, I was able to cold turkey vaping in a way I could never manage with tobacco.

It took being sick for about 2 weeks so I couldn't vape. Once I was better, I just didn't do it again, and it was... actually kind of easy.

Similar situations have happened to me over the years when I was on tobacco, but I could never just walk away like I did with vaping.

Maybe part of it was that, with tobacco, you really organize a lot of your day around it. Going to the store, going outside for breaks, driving a little extra so you can fit in a smoke in the car, etc - vaping can really scramble all that up so you have fewer situational triggers.
