Blimey Copepod, I always tested before meals.
My pre-brekkie covered me for the drive to work, then lunch, then pre-drive home, then pre dinner then pre bed. My stress levels varied greatly from day to day and I knew that by my BGs.
On non-work days - or if I had to leave - for eg a hospital appt! then there would be more tests.
And of course if you happen to go hypo at all, that's at least 2 extra tests if not more if you don't happen nab it the first time you treat it. If you went hypo driving, there's at least 3 tests - ie, feel hypo, stop test, trat, re-test, wait 45 mins, re-test, continue journey.
If you happen to do rash things like exercise - then there's some more tests.
I'm by no means obsessive about testing either, I do want to stress that. Like today I got up latish about 10 am and had brekkie, one test, then didn't test again until 4pm. Just checking my meter tells me I did 58 tests in the last 7 days; 138 in the last 14; 278 in the last 30; 464 in the last 60 and 611 in the last 90 days.
So my average over 3 months is 8 tests a day. x 30 = 240 .......
