I'm looking for some people who had posted in a Forum that they had coughing/choking episodes that were very unique. Mostly you are asleep, coughing wakes you up, you sit up, you start coughing, coughing, coughing, then suddenly it feels as if your windpipe closes and you breathe, talk, swallow, anything!! This lasts up to 30-35 seconds (which seems like forever). It is very frightening! Eventually you can draw in small breaths and the episode subsides...... Has anyone heard of this? Please, please answer me. I've been looking for the people who wrote in before. So far, I've had a sleep study, saw an ENT and need to know what to do next. HELP!!!
