So earlier this week, I got up in the late morning with my husband and went out for breakfast. I dutifully took my insulin once I had decided on what I was ordering, and had breakfast. Later, at work, due for my next injection, I realized that in my just-woken state, I had not realized that I had depleted my store of insulin and needed my husband to bring me some.
It took him just over an hour (my BG was not happy about that). I took my insulin and strangely enough, my BG was higher post-injection than it was before hand. So I took another dose, to bring it down. For the most part, my BG didn't skyrocket, the way I would expect it to not taking any insulin, but it didn't come down either. It stayed either about the same or was a few mmol higher than it was before the insulin. I began to worry. I did not eat a snack. After multiple tests and injections, after 18 hours it was still floating between 9-15mmol. I think I took nearly 100 units (which normally probably would have killed me) without eating and my BG was still almost 13mmol.
Anyhow, my husband had told me I was on my last vial so I took myself to the pharmacy and got some more, though I had sworn I had more than that left. When I put it in the fridge, I discovered that as I remembered, there were three vials of each insulin still in there from the last refill. And then it dawned on me. I used to take Lantus and Humalog, which now that I have extended coverage, I think I can switch back to. (I could not afford to take it for awhile). When I was taking it, I'd held onto a single vial of Toronto that had expired, so that I'd know what the box looked like when I got it from the pharmacy. The insulin my husband brought me had expired in 2009. So on one hand, I felt like an idiot, and on the other, was truly relieved to discover that the high BG was the insulin and not me. Expired insulin has been trashed. I won't be doing that again.
Funny thing was, it did work. It took a long, long time, but I hit hypo at 4.1 for a really brief period of time. I had to take a lot (A LOT!) of it to make it effective, and it was effective for a much smaller window of time. So in an absolute emergency, if you have a vial of expired insulin and it's all you've got, it won't do you for long, but it at least kept my highs relatively consistent, and it did eventually bring me down to normal. I'd expect to go through twice as much of it as normal though. I don't recommend it. But in a zombie apocalypse situation, if it buys you time, go for it. :P
Switched to my new insulin and everything is back to normal. I've been between 4 and 7mmol for two days now, except in the morning, my BG has been elevated. I woke up at 5:30 this morning with the sweats really badly. But I got it managed pretty quickly, so everything is okay. I slept through my nighttime snack.Odd, though. I haven't been up this early voluntarily unless I was actually just up this late. Or due to be at work in the morning. Today I am neither, and it actually feels pretty good.
I've been cutting way back on caffeine. I've finally admitted that caffeine is raising my between-meal blood sugar and stopped drinking it for the most part. Today was my first cup in two days. Of course, that means I've had a really disorienting migraine for the last 48 hours or so. I've been drinking decaf. Coffee flavor will get me through. It will get easier. :)
