This is what I found on-line but I do not use insulin and take my metformin mid day.Dawn phenomenonThe dawn phenomenon is the end result of a combination of natural body changes that occur during the sleep cycle and can be explained as follows. Your body has little need for insulin between about midnight and about 3:00 a.m. (a time when your body is sleeping most soundly). Any insulin taken in the evening causes blood sugar levels to drop sharply during this time. Then, between 3:00 a.m. and 8:00 a.m., your body starts churning out stored glucose (sugar) to prepare for the upcoming day as well as releases hormones that reduce the body's sensitivity to insulin. All of these events happen as your bedtime insulin dose is also wearing off. These events, taken together, cause your body's blood sugar levels to rise in the morning (at "dawn").</blockquote>
