I went to www.askjeeves.com and asked about "Nail Biting Solutions".

Here are some links I found:

http://www.stoppicking.com/

http://www.stopbitingnails.com/

Who knows? Maybe this will help. I also saw a lot of articles (thousands of them), some of them menitioning hypnosis and all sorts of other stuff!

I stand by my original suggestion.......having a pretty piece of jewelry that you want to show off!!!
