I know I have no right to complain.
My site was on day 4, and as an upper-butt-cheek-infusion-set, it has seen quite a bit of wear over the last 4 days.
My 6-day-lifespan sensor was restarted and was on day 8.
I postponed changing my site and sensor last night. "It's wasteful to change a site when I still have a half-day of insulin left." "The infusion set doesn't even hurt that much. I'll just sleep on my other side again tonight." "That sensor worked so well for its first round! It will be fine for a few more days."
The lies we tell ourselves to justify not having to change a site. Not having to feel that jab, twice, as two devices are inserted for 3- and 6- day spans (or 5 and 10, if you tend to stretch out your supplies like I do). All of this led to me sitting at work this morning with a splitting headache and a thirst like you wouldn't believe (I'm at almost 2L of water so far. Been at work for just over 2 hours). Cal reminder alarm prompted me to check my BG and to be quite honest, I probably wouldn't have bothered if not for that alarm. My cgm had me at 8.4 and dropping, so I wasn't worried.
Still, though. I should calibrate.
Fingerstick, 18.6 (335 mg/dL).
Working on a set change with this kind of headache is challenging. I rip open an alcohol swab, then stop. Squint. Rub my aching temples. What was I doing? Oh, right. Syringe, wipe top of insulin bottle. Use now-disconnected pump to calculate the correction dose. Deliver correction.
Another alcohol swab. What was this one for? Wipe top of insulin bottle, feeling vaguely like I've already done this. Think back, pushing through the throbbing haze of red that clouds my head and makes coherent thought a distant memory. Aha! Yes, I did do this.
Do it again. Change infusion set. Charge transmitter. Replace sensor. Look at the mess of medical waste and wonder why I didn't do this yesterday.
