Gracie Ruth is the worse of our 3. She licks everything too. Then, apparently if it tastes 'good' she'll start chewing on it.
Stinker! It is getting better though, she'll be 1 year old this month. She and her brother Yogi both do the puppy licking to fall asleep thing. They'll get all snuggled in with you and as they are falling asleep they'll start licking you. It starts out pretty fast and then slowly trickles off until they are asleep.

I find it very amusing, my DH finds it a bit annoying but being the great Daddy that he is, he just puts up with it, knowing it seems to be something they need to do to fall asleep.
