Your a very common case Mr. Fool.

Your DP raises your insulin need in the early mornings but this need plummets by noon. Your tailing bolus and basal doses are likely double-strength late in the morning compared to early morning which is what is dropping you.

I treat this by superbolussing - cutting my post-prandial basals. As you are not on a pump, a typical solution is to eat a mid-morning snack. If you want to ward off weight gain, perhaps borrow the snack from your breakfast.
