The test you describe is called a glucose tolerance test. You’ll spend a few hours in the hospital, and get back a result that says “you don’t have diabetes”. Whoopty doo. What you want is to find out whether your blood sugar ever goes low, if so when, and what it feels like. That test can’t be done in a hospital, because being in a hospital means not following your usual routine.
