hey, i've never seen that thread before, stupid girl.
i stopped biting my nails for one year now. the thing that really helped was i wanted nice colors on my nails as i was doing for my eyes. so I went to sephora, bought me the nicest colour i've seen, and ordered a growing nails thing from Agnès b (discontinued, shame it really worked !). i took the nail enamel and put it on my night table, so i could look at it and remember my challenge everyday when i woke up. it worked ! after two weeks i had nice nails, and once you've put enamel on them, you don't want ot bite those nice things ^^.
