My basal rates remain steady, throughout the day, except for a few hours in the morning when they're cranked up to almost triple the normal amount to take a bite out of the dawn phenomenon that I've experienced for years. That pesky "wake up at 80 mg/dL but then go up to 200 mg/dL for no effing reason" phenomenon. That midnight - 5 am at 0.45u, then all the way up to 0.85u at 5 am until 9.30 am, when it goes back down to 0.45u mess.
And it's definitely part of the reason an insulin pump works for me, because without the ability to tweak that morning basal rate, I'd be dealing with highs that frustrate me endlessly since they aren't the product of breakfast or stress. They just are.
I forget, though, how important that basal crank is for me. I take basal bump from the pump (two points for rhyming, or for honesty) for granted sometimes, because once it's programmed, it's a done deal. It's not until I travel outside of my timezone that I have to start juggling the dosing details again, making me run low at strange times of the day until my body clock adjusts to whatever timezone I'm in.
This happened last week when I was in Hawaii, which is six hours behind Rhode Island. So noon here in New England is six in the am in Hawaii. For me, that means my body wants the basal rate jacked up at the wrong time, and it results in blood sugars that are tough to track and attack.
Usually, I change the time on my pump as soon as the plane reaches cruising altitude, and I try to adjust to the local time zone as soon as possible. This time, for the first time ever, I forgot to change my pump on the ride home. And then neglected to change it until ... um, yesterday morning, when I looked at my pump at 11 am and saw it boasting a 5 am time. Which explained the weird, ill-timed highs this week in the morning hours and the strange double-down arrows at lunchtime.
And the whole reason I didn't notice the time difference between the clocks at home and the clocks on my pump? What caused this time-insulin conundrum? What eliminated the need to peek at my pump to tell me what time it is?
It's almost too simple. Too ridiculous.
I bought a watch.
