Morning high and also what to eat for breakfasst

Hi All, I started out doing very well when diagnosed and then when I figured out I wasn’t going to drop dead right off----I went back to adding too many carbohydrates and even cookie binges. At my last doctor’s appointment I had lost 10 pounds and had normal blood pressure etc. and then the novelty wore off, the stress came on, and I ate.
I am not on any medicine. If I eat correctly, my BS is fine during the day but it is always high in the morning. Should I not eat after supper or eat something before I go to bed? Also, what do people eat for breakfast as breakfast food is mainly carbs–juice, toast, cereal, pancakes,muffins. I try to eat cottage cheese on toast. I don’t want to eat breakfast meats. I should eat more eggs------Carol
