Shadow, I do something very similar at night, but hadn't thought about the heating pad - I too cannot wear gloves (or socks) the whole night - drives me nuts. The hardest thing for me is during the day - I wash my hands ALL the time, and don't always remember to put lotion back on. Or when I do, 10 minutes later I'm having to wash my hands again....it's a never-ending cycle. I too am more religious about it at bedtime.
I'm hoping that my vitamin supplements will help as well - I've had a bad problem with peeling of my thumb and pointer nails on both hands....not sure why - this has never been an issue before....the other nails are fine. I chalk it up mostly to the fact that those nails are most susceptible to abuse

I also love Butter London Holiday Handbag cuticle oil - I keep it in my purse. It smells divine!
