Keep an eye on Maggie's numbers as you are able. If you are going to be gone, leave plenty of food out. We all have to deal with this, as nerve wracking as it can be, when we're away for hours at a time.
Here I thought she was going to peak at the +6. But I missed the +2 and was a little late.. It was really +3 hours for the 117 BG.
I did make sure she was eating, which is never a problem with Maggie.
