OK, so the honeymoon is over. There's always that euphoria when you start using a new gadget or tool, and it always wears off over time. I'm still glad to have my new Dexcom — believe you me! — because it's helped me out of a horrible motivational slump, and it's made me realize how much of the time I had no idea what was happening with my BG levels.
So those are positives.
BUT... some of the aggravation of my early experiences living with CGM is back.

Who was it that said wearing a CGM overnight could be like having a newborn? Yup, the thing wails at you when it wants attention, regardless of your efforts or needs. I've had some nights where I've been stuffing the receiver in my underwear drawer (inside my new walk-in closet, with the door closed!) so I wouldn't have to listen to it.
That started after one night last week where the thing beeped me awake with a 240 reading and two arrows going up, up!! I stumbled into the bathroom and did a fingerstick check: 140 mg/dL. WtF?
Later that very same night: Beeeeeeepppp! The screen showed me at 50 — OMG! But I didn't even treat that false high earlier. Another stumble to the bathroom: checked in at 95. Grrrr.
Banished to the underwear drawer, you are!
The experts at Dexcom tell me this might be because the sensor was new, and accuracy is always "iffy" in the first 24 hours or so. Hmmm.
But last night, four days into another sensor, same thing: Beeeeeeeppppp! Screen shows me at 50! Stumble to the bathroom, and check in at a lovely 120 mg/dL. This seems to be an overnight pattern. Grrr.
Why am experiencing so many "off" readings overnight?! I'm wearing the sensor smack in the middle of my belly, and keeping the receiver right under my pillow (which makes for much unpleasantness when alarms go off).
I do not know. But it really isn't doing me much good in the underwear drawer, is it?
I've also been on a Holy Mission to drop a few pounds after my post-remodel and post-holiday carb binge. I've been doing pretty darn well for several weeks now: completely off tortilla chips and granola bars, eating only tiny bits of carb in the form of a bit of nutty granola and some occasional apple slices. OK, and a few squares of dark chocolate after dinner some nights (which I dose for profusely).
Yet with all that low-carb goodness, I can't say my numbers have been great. I still seem to spike sometimes after eating veggies with dip, or sunny-side-up eggs with a little coffee. Weird. And the CGM's been slow to catch on to these spikes.
I was shocked to learn from fellow D-bloggers Lee Ann Thill and Kelly Kunik recently that showering is known to mess with your BG levels. What? Just standing under water causes BG changes too? Can they make this control thing any more difficult?!
Anyway, I hadn't really noticed it — or even considered the possibility — until I had the Dex. Now I do notice that I'm slow to come down after a shower. (Power of the shower, or power of suggestion?)
Some Dexcom folks have told me they suspect that showering or bathing may cause accuracy problems in certain batches of sensors. Uh-oh. They've asked me to monitor closely to see if I notice anything wonky after water contact.
Right now, the only thing really wonky is me. Every time something beeps in my vicinity I start frantically rummaging through my purse, to pull out not one, not two, but THREE gadgets I need to check: is it my pump? my CGM? my iPhone?
One or another of my three daughters often perks up with something like: "Mom, it's just a truck backing up over there, see?"
"Oh right, thanks," I sigh.
Then I get the eye-roll. But not before I've rolled my own eyes practically out of my head.
