How to stop biting my nails

I've bitten my nails all my life! I apply nail polish but I just end up scratching it off with my teeth! im addicted. its embarrasing but I cant help it!
I've tried that yucky nail stuff that you put on to stop but NOTHING works! ):
HELP!
oh, and...

please comment on the new pic I took, I LOVE IT do you??

Like any addiction, you need willpower to get over it. You need to mentally notice that you're biting your nails, and once you do, immediately STOP. Every time you catch yourself, stop. Just to put you off it continually, keep using the anti-nail biting stuff too.

Also, keep your mind off it by doing other things. Don't be idle. Keep your hands busy. You'll get over it I'm sure.

I have the exact same problem as you. The only time that I keep my fingers out of my mouth is when I have nail tips put on. The only problem with having your nails done is that you have to have them filled in about every 2 weeks, and it can get pretty expensive! If you can afford to have your nails done and can afford the upkeep you might concider doing this. Also, I love your picture. You are so pretty and have the most intense eyes!

You should try using an emory-board on the edges of your nails.
