text: what could this breathing problem be? every now and then i start yawning again and again, and i can't stop.  i feel like i need more oxygen to stop yawning, so i breath much faster than usual.  sometimes when i'm breathing faster i feel like i'm getting enough air, and sometimes i don't.  this happened to me today,and after a while i got lightheaded, and my vision got cloudy, but then suddenly it stopped, and i could breath normally again.  this happens every now and then but i don't usually feel light headed, and it always stops suddenly.  what could it be? you are hyperventilating, dude.  when you start feeling that way, breathe into a paperbag for a few minutes and it will help you.  godloveya.
