I yawn constantly (no matter how much sleep I get) and it's incredibly annoying. It's been like that as long as I can remember. I have found that after surgeries when I am given a pain medicine like Percocet or Vicodin that I don't yawn while taking those medications! Does anyone know why this is? Any ideas to help the yawns?

Yawning is a normal response to fatigue and drowsiness, but excessive yawning can be caused by a vasovagal reaction. This reaction is caused by the action of a nerve, called the vagus nerve, on the blood vessels.
