@retiredteacher Sorry to hear you were effected by the hurricane. For some reason, knowing that you live out of town in a rural area, I had envisioned you living in the west, like Idaho, Montana, Colorado or whatever!
You mention not being able to eat numerous things "peanut butter, canned meat, chips, crackers, cheese, and those types of things that are not on the list of the Diabetes Diet are all that is edible". No one ever told me that! I eat peanut butter often, cheese, and canned tuna occasionally. There are very low salt brands of tuna now. I sometimes do add mayo to tuna but I also just put chunks of it on top of a salad.
Someone mentioned the nutritional beverages made for diabetics and I do keep those on hand. They make a good, quick breakfast. I will generally throw a can of it into my blender type of machine and often add some strawberries or blueberries to it. It's not bad, I find the vanilla easier to drink in the morning. I love chocolate but not crazy about it in this type of beverage and as far as the other flavors go, I think most of them have a very artificial taste.
