Today my blood sugar didn't go higher than 6.6 or lower than 4.7. And I wasn't even trying. I'm reminded of that quote from the Hitch-Hikers Guide to the Galaxy: "Did you find the right controls?" "No, I just stopped fiddling with them."
I'm T2 and was diagnosed back in 2005, but started injecting insulin last November. I test before meals and before bed, and before excercise if its not in tge normal run of things. But that's because I need to know my the right insulin dose to take, you shouldnt need to be that obsessive if you've just been diagnosed!
