I quit for a couple months in the spring (back at it though unfortunately). Was focusing on like ways to better myself and I’ve always been insecure of my fingers nails which would just make me bite them more.

I don’t chew as much as I used to as a kid, I don’t remember exactly what my therapist said but she said it’s a combination of adhd, some sort of oral fixation and probably some sort of weird perfection thing I have going on

Mavala stop helped, chewing gum helped, and then basically just sheer will power+the ability to always have something else to do with your fingers. I use a stress ball, fidget spinner, and finding ways to rub my fingers on the corner of something when I’m working. It’s doable to quit but it’s just so hard when you don’t even realize you’re doing it. I’m trying to stop again right now so I feel your pain
