It's a myth that blood sugar are low in the morning. I checked mine lot of times and I have always high level of blood sugar in the morning.
I talked with other and they confirm this.
I found a study that claims we are more insulin resistant in the morning, so skipping breakfast or having a small breakfast and indulging a night is better than having an hearty breakfast. Expecially if you're hypoglycemic.
I found relief from morning symptoms when I started to have a carbohydrates free breakfast, a low-carb lunch and an higher carb dinner. At dinner I never experience a sugar crash even when my diet is not perfect.
But the reason why you're feeling low blood sugar symptoms even when your blood sugar is not low, is that symptoms of low blood sugar are not only triggered by low blood sugar per se, but also by a fast sudden decrease in blood sugar.
Reactive hypoglycemia is diagnosed even when your blood sugar never get too low, but they decrease too much too quickly (i.e going quickly from 140 to 70 even if 70 is not low blood sugar)
People with hypoglycemia like us, tend to have poor glycogen control. At night our liver releases too much glycogen and we have sugar highs and consequent sugar crashes, even if eventually the blood sugar at waking time is normal.
