Off topic (and a little foolish)
In my quest for self improvement (including approaching 10 months since my last drink) I would like to stop biting my nails. It is an anxious habit. Half of the time I don't even realize I am doing it. It has gotten to the point, though, where I'm embarrassed to show my hands, they look so ugly. Any tips from former chewers?? (I do of course realize that this is of minute importance in the grand scheme of life, but it does bother me.)
