are you suggesting ocd? because my nails are beautiful because I am so OCD about them.. (I have 5 nail files and 2 buffers for spontaneous manicures) I used to have a really bad problem with biting them as a kid.. and now I went the complete opposite way.
Really.. I am compulsive about my nails... super proud of the fact that I had a job as a hand model :P
I have acrylic nails I have done every two weeks, so there's no nail biting for me. I imagine we all did under different cirumstance at some time of our lives, but it's amazing if you are a nail biter it stops after doing acrylics.
