Very much so. I gnaw at them until the edges bleed at times. I also chew on my hands and arms. I try not to do this infront of others and I remember the strange way Kim stared at me when I started biting my arm. I've tried to stop biting myself for her sake, but I've turned to scratching and now my doctor wants me to go back to biting my nails because it is less destructive.... *sighs*
