Well, things gradually got better over time. The affected area shrunk and peeled less. It was really not noticeable at all and I wasn't really thinking about it much. I have two large spots with thicker skin that peels, and yeah it does peel more when it gets wet. These had shrunk to two smaller spots with a thinner peel, and the more it healed the less I wanted to chew/lick them so it was easier. Of course now that I'm back to square one it's really hard not to pick at them!
I think one of the best things to do is to not lick. That, and don't put anything on them. I'm pretty sure it took my lips a solid six months to adjust to not using chapstick.
