How do you stop biting your nails

Distract your mouth (ie chew gum). Distract your hands by taking up a hobby (ie knitting). Eat calcium-rich foods to spur growth

That's a very hard habit to break. You could try Control-It. It's a cream that causes a bitter taste while nourishing your nails.

You should try nail biting cream. Thanks for using ChaCha!

Visualize yourself with healthy nails, and how great they will look. Pick at least one nail to "protect" at a time.
