I used to bite my nails all the time. In fact, I'm 17 and I just now started to stop. I stopped biting them for about 3 months and had beautiful finger nails and I loved how my hands looked. I bit them off in my sleep one night, because I was so careful not to even break them they were so long, so I know it was in my sleep. Anyways, they are now starting to grow back but they aren't too long yet. I have bit one off again.
What can I do to stop this before it starts again?
