Good Morning Amy,
I'm not sure about the term regulated as far as those yellow AMPS's go - however the important part of what this dose is doing is missing since there are no mid-cycle tests.
If you're working all day and can't get them, perhaps a note on those days would be helpful. Is it possible to get even a 1+ before you leave the house?
I'm basing my comment on this "blood sugar levels should be regulated between 250 mg/dl (13.88 mmol/L) and 80 mg/dl (4.44 mmol/L)" So although not ideal in the 200's, it's better than nothing...and with the proper amount of insulin cats will usually do better as far as hunger/thirst.
Take a look at Patty & Teal'c SS - she works and can't test all night/day, etc. and makes a note on the days when she's working so we don't keep asking her why there are no mid-cycle tests on certain days.
