would correspond to your basal insulin dose.

I think a better choice of snack would be a carb that is slowly metabolized.
High fiber fruit is good, but may not last as long as you need.

Other choices are cheese, some cottage cheese, or the new Glucerna
drinks or bars. These have corn starch in them, to allow slow carbs into your blood. They are very popular here even with the doctors themselves who are diabetic! Do you inject at night? or in the morning?

When you dip your liver then puts out sugar to cover the dip, and that may be more than you need really, so you read high in the morning. Night sweats may be a warning sign of dipping. But with those mattress toppers, you can get warm anyway!

I have heard some pretty scary stories about hypoglycemia in the night from patients.
