Have you seen that episode of Seinfeld where Kramer is test driving a car “for” Jerry and he sees how far he can drive it when the gas tank is reading empty? Eventually the needle “breaks way off” as Kramer and the salesman push the limits of what they (and the car) can tolerate. Obviously that scenario is a bit extreme but I’m sure each and every one of you have tried to go a few extra miles on that gas tank before you final gave in and pulled into a gas station. It’s okay, you can admit it. We all have done it.

(Side note: Do any of you drive super cautious as you approach the last miles of your gas tank and then resume driving like Charlie Kimball after you fill it up? Or is that just me?)

The point of that reference somehow ties back to diabetes if you believe it or not.

The last time I charged my Dexcom receiver was Thursday, October 20. Yesterday on my way home from work I received my first “low battery” alert. I’ve been living on the edge ever since.

It’s 5:00pm now and I won’t be home until at least 7:30, probably later so we’ll see if I make it home on the last ounces of energy left in the receiver.

My theory is that solid blood glucose control keeps the battery life at its optimal lifespan – without having to alert for high or low blood glucose readings it isn’t expending energy vibrating and beeping all the time. I’m not sure if this is true, but it made sense last night.

I suppose it would have helped if I actually tried putting that theory to practice but a 393 mg/dL and a 49 mg/dL over the span of 5 hours doesn’t really help much at all.
