You can buy a glucometer OTC. If I eat poptarts or just pancakes I get shaky sooner than 4-5 hours later. Eating a significant amount of fat and protein with carbs helps me feel good as well as eating at least every 3 hours. For breakfast I usually have 2 pieces of ww toast and 3 eggs (when not pregnant). I need that much protein to help me feel well. Basically, I, for the most part, try to eat what I consider healthy. As much whole food as possible and protein and healthy fats. We limit the junk, although with pregnancy nausea we're falling off the wagon a lot. :tongue_smilie: But I've found that if I eat healthy most of the time I can have high sugar things sometimes and not get shaky. I think a glucometer could be a good investment given your family's history. It can help you see better how different foods, amounts etc affect you. I've never gotten one because with diet changes I feel well.
