Like "Re,e,ber, the heat can play havoc with your readings as well. There is a thread on the site about heat and blood sugar levels but I can't find it right now. I would strongly suggest you AND your wife get into a diabetic teaching class. She needs to know at least as much as you do. If she does all the cooking which I do, is the reason I went and I am a nurse. I learned a lot about feeding my Type II diabetic. He was good about his diet and sticks to it mostly. Occasionally he goes off the deep end. When numbers are out of range, it is always good to review your day or day before and maybe something will stick out to you. Keep keeping on."
