If we try to keep her awake during meals she starts shaking and even going back to sleep. She scowls when we tell her time to eat and even when we get her to eat, even a small amount, she wants to go back to bed. She has apnea and uses a c-pap machine during nighttime hours. She apparently sleeps well through the night. She takes medicine for diabetes so we try to keep her on a regular schedule to avoid complications with her blood sugar level.
