Went low for the first time today, little scary

Welcome. I was in your shoes 3 years ago. In the early days, nothing was more helpful than the kind people on this site. In close second were 3 books that were recommended by none other than the kind people on this site.
1. Diabetes Solution by Richard Bernstein. Read it for the science and wisdom if not the lifestyle.
2. Think Like A Pancreas by Gary Scheiner
3. Using Insulin by John Walsh
Good luck. Believe it or not you will reach a day when "D" is not so overwhelming and all consuming. It'll always be a part of you but, soon you will be in control rather than the other way around.

One other thing to consider, when my blood sugar is falling very fast, I can feel hypo even if the number is normal and even still high. The rate of change itself is causing warnings.

Thanks for the info and book info.

Glad to hear it, John!

The vision thing: No way around that. I had to get new glasses after mine settled, and it did take 5 or six weeks as I recall.

Nothing you can do about it. Chronic high BG means high sugar in your aqueous and vitreous humor in the eye, which changes the refraction index of those fluids (or jelly in the latter case). Getting BG back in line simply changes the index back to what it should be, so back to the optometrist!

30 years ago... hmmm...

Yuppers, the days of stone knives and bear skins when it comes to insulin therapy. Glad your with us and doing well today!

I'd live with the hypos if I could get mine to fall that fast! Unfortunately, with my IR (or whatever it is, maybe just my unique physiology), there is a max rate my BG will fall (while sedentary) no matter how large a swimming pool or insulin I administer.

It's kinda interesting in a way in terms of the CGM graph. Nice little round peak, then a straight-line fixed slope all the way down until 10 mg/dl or so above the final landing, at which the insulin goes 40% flaps, nose up, and glides in for a nice curved landing over the following 30-60 minutes and settles down at the final altitude of the field.

That slope gives me 2 hours min from peak to return. 3-3 1/2 hours after starting to eat. And that's when I manage it perfectly.

Replying to myself, I didn't account for the fact that this is not a fasting response, but a post-prandial response. So there's sugar going in while insulin is trying to take it out.

I suppose there's the chance that I could see a much steeper drop if taking insulin while in a fasting state (like for a correction), but I've never seen it fast then either.

I'll have to experiment a little, very carefully, to characterize this further for myself.

Thanks!

Yup, I think I started on porcine, or was it bovine? Some farm animal.

Anyway, at least I had a BG meter and didn't have to boil and reuse a glass syringe.

They are covered if you have an Rx and are at your neighborhood pharmacy. It does use a rather large syringe. The few times I have had to use it I've used an insulin syringe. Easier going in and that's the point. I think the reason for the larger needle is it is supposed to go into the muscle tissue. If you're thin, and/or your wife can pick a spot without a lot of SubQ fat, you'll be fine.

One thing, since this is your first low, 789 really isn't that bad. But...your body was used to much high bg's. So it didn't feel good. In fact, most MD's will slowly decrease your bg because if doesn't feel right once you reach normal levels if it is done too fast.
