I didn't put this as an emergency, as after Valentino ate quite a bit of high carb dry food, in 20 minutes his number is 278 up from 52 but he is only at +3.5. I'd say he usually nadirs at +5 or +6. Not sure what to do to keep it up. That is with the Alpha Trak ....I had been using Freestyle Libre but it stopped working suddenly. Of course, this happens on New Years' Eve. Any advice you can give would be great. I just think it would normally be heading down but the high carb food helped swiftly. How long do I need to watch ?
