My experience and what I have been told by others is that my morning numbers are higher. If I am watching my carb intake the morning number may be the highest of the day for me. Our liver is doing one of its jobs of producing blood glucose during the night. Obviously our physical activity is nill at that time, unless we are having a very exciting dream (take that where ever you want
) . So assuuming your food intake is under control before bedtime, this "fasting" number is a pretty good baseline of what your body is doing naturally without the variable of what food you consume. Then, based on physical activity, what you eat, meds you take, and stresses in your life that baseline will rise or fall. Right now my morning numbers is higher than most other times of the day - averaging ~155 each morning, but just getting ready and going to work will bring it down to the 120-130 range even with eating a low carb breakfast in the process. YMMV of course.
