I'm not sure the damage from vaping is even close to that of smoking, especially if you smoke a lot. Nevertheless, at some point I decided I was way too attached to it- though I only had a small vape with low nicotine and rather neutral taste as opposed to those things that produce entire cumulonimbi of cherry-flavoured vapour. At least with cigarettes I am acutely aware of the harm, constantly try to keep it in check, and to smoke I need at least to reach an open place.

Btw, one thing that helped me a lot are nicotine patches. I've used them for years and helped me reduce smoking down to ~3 cigs/ day, and even stop it for some period.
