In patients with type 1 diabetes, consuming moderate alcohol (approx. 6.8 units) in the evening significantly increases the risk of next-morning hypoglycemia, specifically after breakfast.

If you have Type 1 Diabetes and drink alcohol in the evening, you are at high risk for dangerous low blood sugar the next morning, especially after breakfast. To stay safe, reduce your breakfast insulin dose, eat a carbohydrate-rich breakfast, and monitor your blood glucose frequently starting from the morning until midday.
