Chewing on lips. How do I stop?

I have a horrible habbit of chewing on my lips, the outsides, but mostly the insides. to the point where I'll give myself canker sores! how can I stop?Chewing on lips. How do I stop?
I had a similar problem with biting on the inside of my mouth and causing my skin to become raw. After I realized I was doing it, I became aware of when I would start biting, then I would force myself to stop. A few times of that and your mouth should automatically know not to start biting or chewing.Chewing on lips. How do I stop?
what you have is a nervous Habit. don't worry many people have this Habit try to relax more and when you notice that your chewing on your lips try chewing gum or chew on a straw.oh now that you noticed it will be easier to stop.
Get some mints ( Scottish ones), Never have that problem again
