For me, the biggest enemy of good diabetes management is denial. In my current situation, it's awfully easy to pretend my diabetes doesn't exist. I suspect I could go weeks at a time pretending that no action, no change, was required of me. Active participation in the online community of diabetics helps prevent that.
One day last week I had a meal that, while not ideal, I've had before without particular problems. (Can you say "five dollar footlong"? Can you avoid singing it?) Later in the evening, I found that I was thirsty. No surprise, everybody gets thirsty now and then. So I had a glass of water and went back to following the DOC on Twitter.
An hour or so later, I felt thirsty again. I think that it's only because I was thinking about diabetes that I got the suspicion that perhaps I should should test. I was 176 -- FIVE HOURS after eating, with nothing since. Heaven know what it had been earlier. After I tested, I tweeted what had happened, indicating my frustration. I was instantly reassured (thanks, Doug!) that bad BGs happen.
So, that night I learned that the five dollar footlongs need to be a part of my past -- unless maybe eaten at TWO meals. I also (re)learned that the support of the online community has become important to me.
We all gotta keep learning, right?
