I was wondering if anyone experiences a deep cough like my dad does periodically throughout the day. We tell him he sounds like a dinosaur. He is on a peg tube for feeding, so he isn't choking on food. My mother said that during the night, last night, he coughed so much that he vomited. This has never happened before. This was followed by hiccups that lasted for a long time. Any thoughts would be welcome. marcia dad 80/10.
