Blood Sugar Variation

Why is it that my blood sugar is higher in the morning than it was prior to going to bed the night before?  For example:  At night it may read 115 (this is approx. 4 hours after dinner, and no snacking).  THEN - first thing in the morning, before I've had anything to eat it reads 135.  After having breakfast, right before lunch time it may be 85-90.  Thanks for your feedback.

I directed the same question to my diabetes doctor a few years ago.

He explained that this was normal and happens because when we awake in the morning the liver will release extra glucose into our blood stream to provide the energy we need to get going with our day. As we get active we will burn off this extra sugar and our blood glucose level should drop.
