Why do I keep waking up coughing and throwing up?

The throwing up may be caused by fluid build-up in your lungs. (Pneumonia) I have asthma, and often, when I am extremely congested, it can lead to me vomiting. My question for you is.... Orange Juice? I can't stand the stuff. It closes my throat and makes it more difficult for me to breathe. Add a little barfing to that, and you're barfing up almost pure acid.... really not good for you. If it helps ease your pain, try diluting it some before you drink it. If it continues, please see a doctor or respiratory therapist.
