I can’t answer about insulin. I have a friend on a glucose monitor and it alerts her if her sugar starts to drop. You might want to post this early tomorrow. I’m pretty late to the game today and there aren’t many comments now.
Worry is hard. I can’t tell you to stop worrying; I would be too. Is there something you find calming? Please listen to what others are saying about good outcomes. Meanwhile, prayers and purrs for a successful surgery and smooth recovery.
Glad you are ok. Hoping the rest get power restored soon.
