This is a sorry post to have to pen, folks. I had such high hopes. I wish the news were better. But after three full months of futzing around with my new DexCom continuous monitor, calibrating and charging and re-initiating at every turn, my A1c has not made significant improvement.
I'm at 7.1 -- up, in fact, from the 6.9 result I got at the (potentially iffy) on-site testing at the ADA Conference back in early June, but still down a hair from my 7.2 result last spring. Nevertheless: Aaaargh!
Why? I just don't understand it. Perhaps it was me; I was not diligent enough...
Oh, but thinking about it, I was. I was! I changed my eating habits, opting for entirely different foods at breakfast, for one thing. I monitored the CGM screen regularly. I checked with fingersticks almost as many times a day as I had before the CGM. I corrected with additional insulin doses ad nauseam. And I exercised regularly, of course, like I have been since long before the diabetes entered my life.
So maybe this is as good as it gets for me. Maybe I'm just one of those people who can't get their A1c below 7.0 without experiencing frequent lows (which I haven't lately). 'Cause the only time my A1c has been under 7.0 was early on in my diagnosis when I was having an average of, hmm let's see, about two nasty lows a day (!)

Here's a peek at a typical week. (For symbolic reasons, I chose the Week of 9/11. Click for a larger view).
Notice how post-breakfast spikes are still a bit of a problem, but only really bad on two of the days. Otherwise, what I see is a lot of time spent in the target range. But Noooooooo. If that were really the case, wouldn't my A1c be a nice tidy 6.9 or less?
So what the hell do I do next? Without an iota of help from my insurance coverage, the DexCom's so darn pricey. I hate the idea of going back to fumbling around in the dark, never knowing which way my BG is headed. But if it's not making a real impact on my future health, how do I justify it?
Oh how painful this is to have to disclose. In my heart I still believe that CGM will revolutionize diabetes care... and it really is just these clunky first-gen products right now that make it so touch-and-go. Once the vendors can tighten up the accuracy of these devices, it will be a whole new era of living with diabetes, I'm sure.
(Right now, however, I'm having an incredible urge to drown my A1c woes in an entire Family Size Sack of Ruffle's potato chips).
