Nicotine is as addictive as caffeine is, your %100 correct that you had a physical addiction to the habit of vaping. But nicotine from a lab (synthetic) or tobacco derived isn’t really bad for you. It’s why snus and nasal snuff have a lot of studies that show neither have any real side effects compared to smoking (and that’s smoking anything). Taper off is best approach, since you can get all the way to 0mg, and even then as you said physically it can still be a challenge to quit.
