Anyone on a weird 3rd shift schedule?

Hi. Ill be talking to my doctor ofcourse but I'd love advice from others who actually deal with this.

I'm type 2 and not doing well. I was just put on metformin and insulin this week. My BS has been in the mid 200s fasting and through the day.

I'm having a bit of an issue wrapping my head around it all with my schedule. Like when to take meds, insulin, and test BS.

I work overnight, 12am-8am. I generally do not eat at work. I could... But not after 4am.

I go to sleep between 1pm-3pm most days.
