  • If your blood sugar < 70 mg/dL, that is hypoglycemia. Follow the “Rule of 15” if this occurs: 
    • Consume 15 grams of carbohydrates, which is about 1⁄2 cup of juice or a tablespoon of sugar, honey, or corn syrup. 
    • Then, wait 15 minutes and re-check your blood sugar. If it is still  < 70 mg/dL, repeat the step again. 
    • If the second check is > 70 mg/dL, consume a small portion of protein afterwards.
  • Be sure to check your blood sugar daily and document the readings.
