I bite my nails. It's a HORRIBLE habit but I just can't seem to stop. A victim of it since I could chew, I look at my stubby, perpetually bitten nails and wonder if I just don't want to stop (there's comfort in familiarity, right?) or if I really have the addictive personality that goes along with chronic vices. When they're polished and pretty, it's a little easier. When I'm chewing gum, it's even better. So I guess the secret is going through a lot of gum. :o/
I wish this were easier. But for now, to help, I'm painting my nails dark red and putting in another piece of 5 gum. Tropical fruit flavor, I think.
