I bite my lip a lot, any suggestions on how to stop beside chewing gum?

There is a product out there that you put on your finger nails that is supposed to taste bad and help you stop bitting them. Maybe there is something similar for your lips?

I have been fighting the same thing for a lonnnggg time. allofus is right, the best thing I have found is the tooth guard. You can find them in the sports section of a store. You dont have to use the whole thing, just cut off a small piece and when it is softened, mold it around your front teeth. It is weird to have something in you mouth but it is the only thing that has worked for me. I actually quit for about 20 years when I was sick for a week. I guess the staying home and resting for a week relaxed me and I kicked the habit till 3 years ago. I had tryed to stop biting my cuticles and was having success but then noticed I was biting my lip again!ARRRRGGGGG!!!!!!!!!

Get a tooth guard from a football helmet, can not bite then.
