I was a compulsive nail-biter for most of my life. I tried putting bandages over my fingernails, painting on that bitter-tasting substance they sell in beauty supply stores, and even putting rubber bands on my wrists and pulling and snapping the rubber bands every time the impulse to chew my nails arose. None of it worked.
Then, at about age 42, I used something that really worked: sheer willpower...and yes, I do have infrequent relapses and bite a nail, but the impulse is now approaching zero.
Sheer willpower! :-)
