I agree with the Nailtiques and cuticle moisturize tips. I used to chew on my cuticles and nails, and hated my hands, but once I got engaged, I hated how my ring looked next to my horrible nails. So I started moisturizing my cuticles and using the Nailtiques to make my nails stronger, my hands have started looking a lot better - less red and swollen. Just having them look a little healthier has made me hate them less! Whenever I'm tempted to chew, I put more cuticle balm on (I carry one of the little Solar Oil balm tins in my purse). Getting a weekly manicure has helped b/c it forces me to get the Nailtiques reapplied! I know I'll never have long nails, but I don't hate the way my nails look as much when the cuticles are in shape and they look healthy.
Good luck!
