My husband was calling this to my attention-when i yawn (not all the time) i make noises when I yawn as I take in more oxygen-I heave and make noise as I yawn-usually several yawns in a row. I may have sleep apnea and have fM and CFS and take meds for bi-polar as well. Also, my sinuses are usually not very well opened in the morning. He said I should yawn quietly. I told him he talks in his sleeps and f--ts . This morning he told me to be quiet about 5:00. I didn't realize I was that loud. It feels great to get that oxygen in me. ???????? Anyone else have this situation?
