What might be different if the narrator got more sleep/.
I have not been getting enough sleep , so I want to yawn all the time -- but it 's very difficult when your back spasms every time you try . And you know when you never get in that yawn you need to get that extra oxygen , you just keep trying over and over , even if it hurts . That 's what I ' ve been doing for two days now .
