I've been on the sensor for the last 5 days. Checking it out to see if I like it. Getting some better feedback about what happens to my blood sugars throughout the day and more importantly, at night. It's been quite the cyborg adventure. Overall good, in the sense that I was surprisingly fascinated by the information it provides as well as loving the idea of getting more accurate data about trends. On the downside was the obvious bummer of one more thing stuck in my body and the fact that at times, there was some real disconnect between the numbers on my meter and those on the sensor when I went to calibrate. The good news is that I'm upgrading my pump because it needs to be anyway. The new one will have the ability by design, to wear the sensor when I want without needing the 2nd brick to read the results, which will be a bit better than this weeks adventure at least. Do I think it's perfect? Far from it! But all things being equal, I'm up for the advancement it represents and more importantly, the potential for a closed loop system in the future. Of course, I'm not thrilled about the design issues, but at the end of the day, I'm on the progress train, looking for any improvement I can get. Ah, the technology adventure continues!
