6 days ago my husband forgot to pick up the dogs food after feeding time. I figured I would see a few days of higher numbers. I didnt think that 6 days and it's still nothing but 400+. I'm weary of testing just to see nothing better. My vial of Prozinc is in the last half of vial. Have had it since 11/11/19. Could it no longer be working or do need to try an increase or a different insulin. How long will an event such as the dog food last? Staying up today till +6 testing every 2 hours in the Hope's I've just been missing something. Going to sleep short before work cause I really need to to see something good. It can't be good to be so high all the time.
