Confessions of an obsessive nail biter

I'm using MFP as a form of therapy. I confessed in another thread about my night time binge eating, and you know what, since then I haven't done that (well it has only been 3 weeks so maybe I'm jumping the gun)! So I'm going to see if it works with nail biting too.

I bite my nails, badly, not to the point where they bleed, but to the point where it hurts because I've taken about half of the nail off, and yet I keep going. I do it at the computer, while reading, in public, yes it's disgusting but I think I'm a tad OCD about it. As soon as I get a little niggle on my nail that isn't smooth I have to chew that right off, and keep chewing until it's smooth. Making it smooth can't be achieved by biting, and a nail file won't do, that won't make me have the same sense of satisfaction, or I just end up filing way too much off my nail. I literally can't think of anything else, can't do anything else until I have obliterated that nail! I find I end up with my nails in my mouth without even realising. You have no idea how many bits of fingernail come out of my keyboard, how gross is that! I've tried the yuk tasting stuff, I've tried fake nails, but the only that stops me biting is being on holidays, and then it starts right back up when I'm back to normal life.

But it ends here. I will not give in to the OCD, I will bath my hands in nail polish remover if I have to so it smells so disgusting I won't even be able to get my hands near my mouth. If I find my fingers have mysteriously appeared in my mouth, I will deal with it the same way as having a naughty snack, accept it and move on. You all are my witness

Anyone else want to decide to stop nail biting or have a habit they need to confess?
