Blood Glucose Self-Monitoring Improves Metabolic Control in Patients With Type 2 Diabetes

This is one of those things. I can tell you for a fact that my blood sugar readings go down when I do cardio exercise. Thus, I'm more apt to do them the next day.

Unfortunately, it costs around 80 cents every time you test. Before insurance.
