how do I stop my habit of biting my nails
There are spicy/bitter sprays or glosses you can paint on your nails. When you bite them, the taste will be so awful you'll soon break the habit.
Bad habit ,don't do it
Put hot sauce on ur finger nails or dip the tip of them in vinegar
cut it down! u can not bite ur fingerright?
make it a game see how long you can go with out biting them.
