Emails and comments from fellow DexCom users are starting to pour in, and the split in testimoniesStairs is quite striking: on the one hand, lots of folks are disappointed -- even disgusted -- at having invested so much hope and money into "a lot of expensive, inaccurate numbers." On the other hand, I've got people telling me that the technology has saved their life -- as in rescued them from hypoglycemic unawareness -- and/or helped them finally hammer down their A1c after years of struggling.

This is not just about the DexCom product, either, since I'm getting notes from MiniMed Guardian RT users as well. They're equally elated or exasperated, it seems. There appears to be no middle ground when it comes to trying these new CGM devices: you either love 'em or you hate 'em. Which means a few interesting trends are in the works:

* In terms of "viral marketing" (word-of-mouth endorsements), there are strong mixed messages shooting about, which will make for a lot of ambiguity in the marketplace, I think. Once the new, improved, next-generation devices are ready for sale, will people want to jump in? Or will they have heard too many horror stories from the "Downstairs" group?

* A grassroots resale market is quickly developing -- meaning that people who've tried the products and want to opt out and recoup their money are looking to resell unused sensors and even full systems via the web. If you happen to be an "Upstairs" user, start checking D-message boards (and maybe soon eBay?) for discounted CGM supplies soon.

(I also understand there's quite a {black} market for profitable resale of traditional glucose test strips. Read all about the Test Strip Thiefs here!)

In any case, you all know that I've been planted very squarely in the Upstairs camp on the CGM issue. But on this trip to Europe, I feel myself slowly descending. My experience here has been primarily a pain in the Arsch: the unit is so consistently off that I had to put in isolation overnight to avoid being woken by never-ending off-target alarms. In the morning, I'd try to recalibrate, but found that most days it took me well into lunch to get the device going again, only to find that it was still way off! Running around 70, when truly I was at 120 or above. Aaargh! Lots of time spent charging the unit and feeding it fingersticks, without a lot of value coming out the other end.

But I'm not giving up. My plan is to wear the thing for a solid three months in order to see if my A1c is truly and significantly improved. If yes, I remain Upstairs. If no, I dawdle about the staircase, trying to decide what to do next. Cross your fingers for me, Upstairs gang!
