Does anyone else do this?
It started when I was a young child and I've never stopped.
Its a nervous, boredom thing but I suffer with mouth ulcers because of it.
I've tried stopping but when the skin heals, it becomes bumpy and the urge to bite that off is inescapable, so on it goes.
I hate it. My face must look horrible when I'm doing it and my mouth is always sore.
What can be done? Has anyone ever stopped doing it for good?
