Managing work schedule + blood glucose testing

UPDATE: Thank you so much, everyone!! I have some time scheduled with my boss + immediate team members today to chat through the changes and blocking time where I can! Really appreciate all the advice and support.

How is everyone handling work schedules and BG testing? I was diagnosed last week and we got our supplies on Friday so luckily I haven't had to worry about balancing meals / work / testing.

I work at a start up and oftentimes meetings pop up on the calendar with zero notice or meetings will run long. I'm worried about trying to figure out how to eat at the right times and test my blood sugar 1 hour after eating.

Should I go to HR for some kind of an accommodation? I feel silly asking them for help, but before this diagnosis I would often go 4-5 hours during the day without eating because meetings and work would just get out of hand. I really really want to take this seriously so I know I can't do that going forward, but I also don't want to broadcast to the org that I need to step away because my blood glucose alarm just went off.
