How do you stop biting your nails without using that bad tasting nail stuff?

About 30 years ago I decided I had to quit biting my nails and what I did was replace the urge with biting with something else. I realized that one reason I bit my nails was when I felt a uneven edge or a break so instead of biting them I got a file and started grooming them. It did the trick. Now I carry a file in my handbag, have them all over the house and I don't bite my nails. Maybe this will work for you too.
