If you mean after just eating, the answer is no. Sugar level should rise after eating, and then fall gradually.
i had my sugar tested right after lunch b/c i was still dizzy and the lady said Have you had anything to eat? i said yes i eat more then most people every two hours. i have 3 meals and about 4 snacks. granola, nuts and peanut butter are my biggest snacks.
You sound like you have hypoglycemia. You are correct to have several small meals. For snacks protein is best because it is digested slowly. I keep boiled shrimp in the refrigerator and use them for snacks. You must stay away from sugars and anything that easily converts to sugar. Are granola bars high in sugar. Better check that.
the gronola probably is..
