There are products on the market that you can apply to your nails so that when you start biting, you get a horrible taste. I dont know any specific names but have a search on the internet see what you can find.
There is this cream that you can put on your nails that tastes horrid so you don't go near them, I'm not sure where it's from but all my friends said it worked for them
paint them or if you bite your nails daily them put nail polish remover on them everyday.
Paint them. Get a manicure. Eat food or chew gum to keep you mouth busy. Sit on them.
File them smooth, then paint them, and keep them painted. Works for me.
Paint them. Then, if you bite them, you'll get sick.
take vitamins and they will make them stronger and better looking and this will make you stop biting your nails
