...OP, I feel for you because, although I also hate to bring this up, my mom started a recent habit of licking her lips ALL THE TIME - while she's talking, while she's eating, if she is relaxing (watching TV or solving a Soduko puzzle), just ALL THE TIME. At first, when I noticed it, I had asked her about it and she said that her lips were dry, but it's gone WA-A-A-AY beyond that. She doesn't even realize that she is doing it! Does anyone know if it's just a habit that she now cannot break, or is there some underlying medical issue that she should have checked??
