Loki also has this lovely nervous habit. I find that he does it less when he has something better to chew on, like a bully stick. I try to interrupt him/distract him when he does it and I give him a reward when he stops. Sometimes I give him a time out or at least ask him to get off the couch and move to the dog bed if he's going to do it. I also have found that wearing him out helps, since he sleeps rather than getting bored and licking.

Sammy also does the licking your hand/nose/etc. thing. She even goes around and licks floors and things. I haven't figured out how to stop that habit yet. It's gross.
