Like "My son is T1D and his levels are always bouncing in the 200's. His last A1C was 10.3. He is active and eats very healthy. Avoids sugars. He take Lantus at about 10pm and Humalog with each meal. You say your carb ratio is 1:10. Can you explain to me what that means. He has tried counting carbs as servings but can't seem to figure how many units to take per serving. Usually not enough. Can anyone help with this? "
