One of the most useful things I have done recently is had a continuous blood glucose monitoring system fitted by my diabetes team. I had to wear it for 6 days, making a note of all my food, insulin, blood test results (to ensure the sensor was functioning correctly) and exercise. I then went back for an appointment today to discuss the results, and it was fascinating to see the consistency of where highs and lows were happening. If this is something your diabetes team offers, it is a really worthwhile exercise. It will give you a much clearer picture of where your highs and lows are, and if there is a pattern to them. It will also get you to focus on your injections and food intake, and just doing that can also improve control.
