Let me ask if you even know why you are testing. There are in fact many reasons to test. I've found that when I associate testing with a reason, I pretty much have to test. I am contemplating writing an article about my thoughts, but in a nutshell here's some things you can do.
Basal test - what happens when you don't eat? What happens in the middle of the night? Does your basal insulin keep you flat? Does it last 24 hours? Are you in danger of going hypo?
Meal profiles - How quickly does food make your BG rise? Whole wheat vs. white bread? How quickly does your meal bolus work? Do your food and insulin profiles match? What adjustments can you make to make them match?
Compliance - Now that you understand your basal and meal profiles, you actually have firm expectations, are you meeting them? If not, how do you correct?
Activity - what's the impact of n minutes of walking on your BGs? Of an hour if anaerobic competition? Of a four hour round of golf!
Rebounds - you've had a doozy hypo. How long does the hormone dump affect you and by how much? How are you going to treat the next one?
Stress, sickness, weather, sex, blah, blah, blah.
You can get rather anal about such things. You can get lost in your tester! Be realistic. But testing with a purpose makes a huge difference!
Start with the top two. They're the biggies. |
