    When do you test your fasting blood sugar

    Do you test it immediately upon waking?
    An hour after?
    Last night I went to bed late, around 11:30PM and had a glass of hood chocolate milk (only 5 carbs and sooo good if you haven't tried it!) but I woke up this morning at 7AM so it hadn't even been 8 hours. So I just took my blood sugar around 8:45AM and it was 117 (low for me!)
    Is this OK or should I be taking it ASAP?

    I test mine when I wake. My problem is, it carries on rising until I eat something, so it's important to be aware of that. I think a lot of people have the same problem.
