Hi - always recommend checking in with your doctor/care team for more individualized advice and responses - and as we cannot offer medical advice.
Nighttime snacking can sometimes help manage morning blood sugars (which may be high due to the dawn phenomenon) - https://type2diabetes.com/nutrition/nighttime-snack-blood-sugar-must but also depends on what and how much you might be eating.
That might affect blood sugar levels which can affect numbness ( https://type2diabetes.com/symptoms/numbness-tingling ) Will let you know if I see others discussing this in the community as well!
