My Dexcom had a day or two of throwing triple question marks. And then it spluttered. And died, offering up the CGM-version of the "blue screen of death." That error stayed stuck on the screen no matter what buttons I pressed or how often i swore under my breath.
After emailing the team at Dexcom and speaking with my representative there, I was waiting (sort of) patiently for the Dexcom to arrive. I don't often go more than a few hours between sensors swaps, so being without the Dex for 48 hours felt creepy.
And it was a long two days. I didn't realize how integral the Dexcom routine was to my schedule before the thing busted. Even though the receiver was dead, I still found myself bringing it everywhere. I still brought the receiver to the gym with me. I kept clicking on the screen and remembering "Oh, the error. Shit." And it still ended up on the bedside table, even though it wasn't technically working. I also did that strange "take your pants off carefully to avoid scraping the Dexcom sensor from your thigh" thing, even though the sensor wasn't actually on. (I felt like a diabetes mime.)
The most mental adjustment was the "before bed" routine. Normally, I do the bedtime bit (wash face, brush teeth, put the horrible, old-lady Muro 128 in my eyeball thanks to the Bird talons) and then snuggle into bed. But the very, very last thing I do before bed is test my blood sugar, and then check the Dexcom graph. Mentally, I need (want?) that security of knowing where I'm at before I embark on
eight (HA!) six hours of sleep. Seeing a blood sugar snapshot on my meter is one thing ("Okay, I'm 143 mg/dL.") but seeing where that number came from and where it's going is another. ("Okay, so the Dexcom says I was 212 mg/dL before but now I'm 143 mg/dL with double-down arrows, so I might grab a swig of juice before going to bed.")
So when the new Dexcom system arrived yesterday morning, I couldn't wait to slap this Bad Larry on. I felt like I was flying blind for a few days, and I wanted the new sensor queued up as soon as possible. I was almost as excited to see that FedEx box as a certain BirdFace was:
It's strange, what becomes part of the routine. Strange to tote that little egg-shaped receiver around with me everywhere. Strange to miss the sensor stuck to my body. But on Sunday morning, when I woke up with a blood sugar of 42 mg/dL without any symptoms of the low, missing the CGM didn't seem strange at all.
