Thanks
So on sleep mode, will it increase basal if you are high?
Yes, CIQ will increase basal slowly to counteract highs. I don’t eat within 4 hours of going to sleep and try to get any highs under control beforehand. But the few times that I was higher than I would want, CIQ took care of them.
Just a quick update, our 5 days with Control IQ were tough with tons of lows, but it turns out my daughter’s bad habit of bolusing AFTER a meal were the cause, she would bolus when the pump had already corrected her. So now she knows and has been making a huge effort to bolus before. Who knew the control-iq would have this great side effect? 
She was still having quite a few lows, so we’ve reduced her insulin which is also great. And Now her average blood sugar is 9.1 and she’s spending more time in range.
So this has been a huge game changer for us and I’m super excited.
And @FatCatAnna, I know it’s tough with the G6 being so expensive. We get coverage from ACSD thankfully but I know that if we lose that we’ll be paying $300/mth for the G6. Where abouts are you in Canada? I have some boxes of G5 Sensors that I could send you if you want!
We are about 2 weeks in using control IQ. We’re in Ontario. We just found out a few nights ago that if you rely on sleep mode to bring you down from a higher blood sugar, the basal insulin seems to stack and ends up kicking in with a bang. So I guess our lesson here is to get back in range before sleep mode kicks in. youdoodle-2021-04-20T06-45-11Z|365x500
You might review you have the correct correction factor set in the pump.
The whole point of these pumps are to keep you in range whether it is sleep mode or standard CIQ.
Yes, we have since strengthened the correction factor to bring her back in range better - particularly before sleep mode turns on. I wonder if sleep mode uses the correction factor since it doesn’t give bolus corrections.
One thing I have learned in my 4+ years using DIY Loop is that letting a weak correction factor (aka insulin sensitivity factor) chug along over many hours is that the cumulative effect (stacking) of the boosted basal eventually gains the upper hand and then overwhelms the glucose and drives it into hypo territory.
I’ve also noticed that these basal-driven hypos are more tenacious than bolus mistakes and require sustained simple carb treatment without over-treating, a difficult tightrope to walk.

Thank you Terry. That is what I suspected. And with CIQ giving only 60% corrections, it would compound the problem of drifting higher and higher throughout the day.

The fact that changing to Control IQ eliminates Basal IQ has kept me from changing.
However in changing to Medicare, I received a second T:SLIM 2. I am considering changing one of them to Control IQ to give it a try.
I am a low carb eater and have HgA1c of about 6.0 on the Basal IQ so wondering if the change is even worth it!
I have control IqEssentially it’s like having basal Iqplus automatic bolus. I know they don’t work exactly the same way, but I’ve used both and I see no difference. I never let my sugars go high enough for the auto bolus to deliver, I always do a correction before my pump gets around to it.
So essentially the control IQ will fix high sugars on its own. And it does work, but if you are one of those micro bolusers , like me you won’t see much difference. That being said, I’ve woken up in the morning and see that it’s given me a correction late and night with no alarm, I was racing up to 160 and it headed it off and brought me back to 118 before I woke up so it has its benefit

My understanding is that Control IQ is Basal IQ plus more.
I have CIQ, and use sleep mode 24x7. Sleep mode target is 112.
If I time my bolus right, all is pretty flat, or if it alarms high, I will do another bolus. Sometimes a ‘overbolus’ works well, and the reduced basal after meal balances out.
Once delivered, insulin doesn’t know that it is basal or bolus. With CIQ and sleep mode 24x7, it works well for me, A1C around 5.5 since CIQ with less effort than previous medtronic 522 pump.

This is kinda true. The big sticking point is for those who can’t accept the 110 target, instead of 100. Basal-IQ doesn’t have the ability to reduce basal if you’re predicted to be under 110, like Control-IQ does. It’s just a hard stop on basal (I don’t remember where exactly, 80 mg/dl I think) and an automatic resume once BG changes direction.
Control-IQ is actually better at preventing lows than Basal-IQ, since it can reduce basal sooner and soften the landing, but the trade-off is that it’s really difficult to stay below 110 for long. For some people, that’s a deal breaker.

As one at the far end of the age spectrum I have limped through the control-IQ for a year now. I realize as i read the posts here that I have never used the sleep mode for sleeping! And yet, I sleep through the night whereas I did not before ciq. Also, the times I eat a dinner that is half potato or rice and half ‘good’ veggies (dark greens/various other good vegs), with a small amt of pro. like shredded cheese or beans, my BG line runs about 103 all night long. I don’t think my trainer taught me the sleep mode and it never occurred to me but I have read about it a lot here and never understood it. But I think I do now.
It sounds like it would be great for a teen or younger for sure.
