So, as I sit here having been woken up by a blood sugar of 2.2 mmol/L (40 mg/dl)—don't worry, I've eaten Skittles—it got me wondering:

At what level do you typically wake up from a low blood sugar?

For me, you're pretty much looking at it.

Except on occasion, I might wake up around 3.0 mmol/L (54 mg/dl) if I haven't had any low in the previous few weeks (which means I'm almost definitely running too high in general).

Otherwise, around 2.0 - 2.2 (35-40 mg/dl) is pretty much it. (I do feel lows at higher levels during the day. Just for some reason, if I'm sleeping, I get this low before I wake up spontaneously.)

What about you?

I don't have a BG level, it's more the time and the escalating bleeping on the CGM.

*waits impatiently for Dexcom in Canada*

crap thats low! do you use a bottle full of lantus a night?!! ;)...the lowest i have woken is 3.9mmols and that was this morning and that wasnt due to being low, that was just up time and my fasting reading!
You sound as though this happens quite often, its a bit of a worry!

It kind of freaks me out that I need to get so low to wake up. I mean, that doesn't leave a ton of room between waking up and ... not waking up. Overnight lows don't happen too often (and almost always have a cause), but I've just had diabetes for over 20 years so, cumulatively, I've experienced a lot of lows over that time.

As for last night, I exercised and didn't set a -10% temporary basal rate before bed (because I've been running high lately, figured I didn't need it), plus went to bed with a bit of insulin on board. So I was pretty much asking to go low! (Plus I'd had a low the night before last, and once I go low once, the next one doesn't take much effort; it's like my counter-regulatory system is fried for a bit.)

I've woken up twice in the night with a low during the past year or so. Both times I was in the mid-50's mg/dl (3-ish mmol/L.)

That must be my magic number.

I'm glad you're OK. 2.2 (40) doesn't sound like very much fun to me.

I'll usually get woken up in the low 50s/high 40s.

The lowest I woke up at was 25 when i accidentally took 30 units of humalog instead of lantus!

Yikes! That's definitely too low for comfort.

yeah, i had to eat about 350 carbs just to get it above 60 again!

If I'm lucky I'll wake up from a low around 3.0 mmol/L (sometimes when I'm in the 2s I'll moan and wake myself up, but not usually!) - lower than that I rely on my cat, dog or husband (in that order! LOL!).
I also seem to wake up around 3 am(ish) and will often check 'just in case' but I think that is a habit that formed in the years of bad control when first diagnosed and then reappeared when I was pregnant and testing every 2 hours...
Hope the Skittles brought you back up :)

I wake up at 3 a.m. often too but for me I think it's tied to something hormonal. I will often wake up with hot flashes, look at the clock, and, yep, 3 a.m. I wish I understood how all that works.

I don't always wake up, but if I do wake up randomly in the middle of the night (and don't immediately know I'm low), I always check just to get a record of what my BG is doing in the middle of the night.

Yeah, the Skittles brought me up ... and so did the granola bar, almond milk, granola (not in a bar!), and bite of muffin I ate after posting this!

Brought me up to 13.2 mmol/L (238 mg/dl), in fact. Ugh!
