Control IQ Help

In the past 3 months my SD and average BS have risen due to me not being able to figure out how to maximize my control. I have read other posts and for a time was very successful with being in sleep mode constantly. For 3 months I have struggled to maintain an average blood sugar below 120 and my standard deviation has risen from high 20s to high 30s. This seems to be a result of Control IQ constantly lowering my basal and/or the resulting rise in BS. With an average blood sugar of 136, I am not staying in sleep mode range. My basals are hard to evaluate since it is such a bumpy line but I have tried both lowering and raising basal rates while staying in sleep mode. My control does not seem better either way. Is it time to get rid of sleep mode?
Ideas?

Sleep mode targets 112. And I use it a lot, but when I’m working I turn it off so I can get correction blouses automatically.

But it targets 120 without sleep mode on.

I have several ways to bring down your average glucose if you want to try.

  1. Tell the pump you weigh more than you do. This will slow down the switching off of insulin a little bit on the algorithm.

  2. Decrease your insulin sensitivity setting )this is dangerous unless you know exactly what you ar doing and have been doing it for a long time)

  3. My new way to do this is to make all the settings normal, the way your doctor set them up, but take 10 units of lantus every day in addition to your pump.

I tried several doses and 10 seems to work for me, but im 200 lbs and 6’3, so don’t rely on my settings

My sugars run lower now over night I average 95 with this method, and it also prevents those stubborn highs.

It also reduces standard deviation and time in range. I suggest if you are going to add lantus or another long acting, you start with a very low dose to see how it goes, and if you can get a buy in from your doctor, even better

My insulin needs vary a lot day to day, between different activity levels, hormones, inflammation, etc… I feel like I’m forever tweaking. Things work great… And then suddenly, they don’t, and it’s back to tweaking again.

Increased standard deviation usually means my correction factor is set too low, meaning the system is too aggressive and Control-IQ is over-correcting on both ends of the spectrum, and taking me for a nauseating roller coaster ride. Simply raising that setting to a slightly higher number settles the line down. Of course, other settings might need tweaked too, but I can’t see those patterns until I calm the standard deviation down.

I think there’s a tenancy to run aggressive correction factor settings, because it gives Control-IQ more power to lower BG. But too low can actually be quite problematic. For reference, I think of my “true” CF as being 1:46 (though in all fairness, I haven’t tested this in a long time). I find anything lower than 1:43 sends me crazy, and I usually use 1:44 or 1:45. But even those numbers are written in pencil, as my needs change.

This helps but oh I just realized that turning off control is does not turn off the adjustments to basal??? That is surprising but it is still turning off my basal if I drop below a certain blood sugar ? Ugh! I hate that!
If I unpair the pump will it just run my basals as set without adjustments? Will the pump beep at me for doing this?

I turned off CIQ, and do not get basal suspend or adjustments. Basal based on profile setting, which could be set up for different rates throughout day.

If you want auto bolus off,then use sleep mode.
Sleep mode does not bolus and only controls basal rates

I don’t think you’ve actually turned Control-IQ off if you’re still seeing suspensions. Perhaps you just turned off the sleep or exercise activity? There is an absolutely zero insulin intervention when Control-IQ is turned off, unless you do it yourself

There is a toggle button to turn Control-IQ on/off. Options> My pump> Control-IQ

Once it is turned off, it will only deliver your programmed basal rate or set temporary basal rate and not make any adjustments nor give automatic correction boluses.
