I'm 25. My entire life I've had difficulty breathing from my nose. I thought it was normal because thats how its always been. I developed bad habits. Breathing from my mouth, keeping my mouth open (while awake and asleep), breathing through mouth while eating, etc. etc. Now, after two surgeries (turbinate reduction, septoplasty, revision septoplasty/rinoplasty), I can breathe great. But I still find myself subconsciously breathing through my mouth. What can I do to break these habits?
