Last night I was talking to DH trying to figure out what could be the cause of the higher trend and lack of greens. The food is the same. We don't think there's been any contraband. I think I'm testing enough to catch any lows. We thought maybe it's the tail end of the FIC flareup even though she hasn't shown any physical symptoms of it since 4/12. So we landed on that it must be the vial of insulin that is 4 months old losing efficacy.
Today has taught us that the insulin is fine and the answer is Just Cat .
