Here's the playbook: stop licking, ditch the tingly balms, and apply a thick, boring ointment at night. Use a humidifier. And maybe don't sleep with your mouth wide open like a tiny furnace.
Your lips will probably still get chapped sometimes. That's okay. It's part of being a human with an exposed, leaky, wimpy mouth. You're not broken. You're just delicate.
So go ahead. Apply that balm. Accept the mystery. And maybe stop sniffing that sour orange. Your lips will thank you later. They're actually pretty polite when you stop torturing them.
