I have a friend, who is a bit overweight. She falls asleep everytime we attend functions where our attention is required, and her mouth drops open and she begins to snore and jump. I will nudge her, and she'll wake up, only to doze right back off. Some people who sit near us, will ask me, if she's ok? If she's holding anything in her lap or her hands, it all hits the floor. Once the function is over, she wakes up, and doesn't go back to sleep. What could be her problem. Is this what sleep apnea does to a person?
