This often happens just when you fall asleep and you lose conscious control of muscles but it happens during the day too. If you have frequent bouts of coughing at night, it can be caused by food and liquids eaten earlier in the day that come up when you lie down and then go down the wrong way into your windpipe and into your lungs. If you hiccup after eating, it can be caused by food building up in the esophagus that presses on the diaphragm. There is no bile so the food tastes the same as when you swallowed it. When you regurgitate you expel food that has been stored at the bottom of the esophagus that has been unable to get into the stomach. It sounded more like they were regurgitating. I doubt if the original poster was vomiting. You have to have special tests done to see how the muscles in your esophagus are working. None of this can be seen with an endoscopy (although if the procedure is painful that is a symptom of a problem with the stomach valve). I would have to spit out saliva because it wouldn't stay down. Very cold drinks prevented me from swallowing anything for at least an hour. Muscles in the esophagus can be very sensitive to temperature. The mucus is probably just that -mucus from your nasal cavity (that normally drains down the back of the throat so you are not aware of it) that came back up again just like the saliva. You are constantly swallowing saliva and if you have an esophageal problem it can come right back up. The foam that someone described is very common with esophageal movement disorders-it's just saliva. I used to get this all the time before my surgery. Sometimes the spasms themselves can feel like you are trying to swallow broken glass. Instead of going down, food goes part of the way down and then stays there so you have that stuck in the throat sensation, or it goes back up again. Any information you can provide will be greatly appreciated. We have noticed the condition when eating the following foods (rice, beef, fries, and foods with sauces). My 19 year old son has also developed the same condition. It happens at home also but not as often. It is starting to become embarrasing as this will happen when eating with friends in public.

But after the episode is over, many times I can proceed eating the same meal. Initially, I tought it was an allergic reaction. There are no other symptoms and I cannot predict when it will happen. And there have been times when I have been unable to make it to a restroom or other appropriate place before the mucus comes up. I sometimes feel as if my throat is starting to swell. When I vomit, most times food is not produced. For several years now (at least 17) I have experienced a condition periodiacally, where after I take a few bites of food, I will immediately have an uncontrollable need to vomit.
