High morning readings could be caused by anything. Restless night, nightmares, hormones... It's the testing you do around meals that is the most telling. (Test before and 2 hours after the first bite. You want a rise of 2.0 mmol/l or less, and to stay below 8,5 over all.).
The bulk of us have had little to no guidance from our GP's, nurses and endo's, and what information they do have is often hopelessly outdated. Meaning that your being proactive right now, is going to make the biggest difference. Good on you!
