For the hell of it (and to prove to myself that it's not a habit), I stopped biting my nails on Jan 1. I always maintain that I broke the habit years ago, and that biting my nails is part of grooming now, not an unconscious habit. I'm usually fairly conscious about doing it.
And apparently I was right. Not biting them doesn't bother me in general, but having any kind of nails messes up my typing! Using a computer is annoying to me with any kind of nails
Over a month later, I haven't put my nails in my mouth. I wonder how long I have to do it to prove a point, I miss having ubershort nails and I hate the feeling of clippers!
I stopped for a good two weeks, but have since relapsed. Bit two of my nails to the point where pressure against them hurts. Typing is semi-painful when your thumb/pointer are in pain when being used
As someone who bites their nails, DON'T GIVE IN. You know it stinks.
