So this was last night:
Went to bed after a little bit of a spike, bolused it down conservatively because I was going to bed, but then woke up at 4 am and saw a steady, red line on my Dexcom graph, showing that I was not only in the blood sugar trenches, but had been there for a while.
The problem is, it wasn't the low alarm on the Dexcom that roused me from sleep. It was the sound of my daughter yelling, "MOMMY AND DADDY!!!" through the baby monitor (which I will use until she's at least ten thousand years old) that vaulted me from the bed.
This is a problem, and one I've always had with the Dexcom alarms. They are great - and plenty loud - when I'm awake and driving, or playing in the garden, or on run. I have no trouble responding to them when I'm wide awake and tuned in. But when I'm asleep, and low, those alarms rattle on without a response from me. And that unnerves the eff out of me, because nighttime lows are what I want the Dexcom protecting me from the most.
I've done the Dexcom-in-a-glass routine, and I'll revisit that strategy again tonight (I took a break from it after switching to the G4, as the alarms were notably louder than the Seven Plus), but these kinds of lows make me nervous. I don't respond to them as well as I used to - last night's low made me feel like every move my body was making was through a pool of thick, overcooked oatmeal, putting a definitive drag on my muscles and my mind. Once I had a few glucose tabs (and confirmed the low at 49 mg/dL), I still needed a hit of juice to push that sloggy, thick feeling away from my synapses and give me the wherewithal to go back upstairs to bed. (Where there was a three year old recovering, post-nightmare, and hanging out with her dad.) And once the low is over, I don't bounce back the way I did years ago, either. A blood sugar under 60 that makes a middle of the night visit wrecks me up a bit until I'm well into my
second fifth coffee the following morning.
This morning, thanks to lows and nightmares and the quiet of a house that isn't overrun by singing, springtime birds nesting outside of our bedroom window, the whole family managed to catch a little sleep-in. But I feel slammed, and sometimes I wonder how many of my brain cells are surrendered during those graphed red lines. (As evidenced by the fact that it took me three minutes to remember how to make pancakes this morning, and it took me 30 full seconds to find my insulin pump, which was attached to me, what the eff.)
