With IDDM, his nighttime routine includes a snack and insulin injection approximately 1-2 hours
before bedtime. My wife and I wonder whether this has a big effect on his lack of sleepiness. Generally, the snack is low in refined carbs, but has appropriate complex carbs (crackers, popcorn, pretzels, breadsticks, etc.) and always includes (cold) milk. In general, is a high blood glucose level going to mean a more alertness and less sleepiness?
