I had the same problems where I was coughing so bad I'd lose food in the mornings. So before I got up I changed the routine to allow a coughing session.

First I'd clear my mouth as best possible using tissues, kept the cool air humidifier on & played my video game while resting @ an incline. Strangely the video games Columns & Tetris kept me focused on something else entirely that I relaxed enough to keep from that gaggy hard cough from happening. Once I felt ready & cough free I'd eat...er, inject my Osmolite breakfast. Hope this helps, good-luck!
