Here is something you might consider. A cell for, or if you are way out in the sticks, A satelite phone. I think a sat phone can give position and you can call from anywhere even if there is no cell sewvice. You may also carry aGPS as with this you can tell you exact position. Take all of the other precaustions. Mydiabetic best friend and I hunt together but hes is still not on the insulin shots. He makes sure he is regularly eating (5 or 6 small meals a day) and always has diabetic friendly snacks with him. He schooled me one what the symptoms of a diabetic episode look like.
Have you asked your doctor about hunting alone?
