why do I have a habit of bitting my lips all the time?

Do you do it when you are nervous? I think it is a nervous habit.

I do it when I’m bored. You just have to become aware of when your doing it and break the habit. Also try chewing gum, helps with me.

I do this constantly. It is really gross.

I’d like to know too…I bite the outside of my bottom lip…

to much lithium

Maybe your lips are to dry. Try Chapstick. Either that or you have an oral fixation. ...If you have an oral fixation then please contact me privately for further direction.
