Hi everyone - I just got my Tslim pump this week and started on Control IQ. So far, the day-time numbers have been AMAZING and my exercise numbers have been AWESOME - I’m so glad I got the pump! However, I’m really struggling at night in “Sleep Mode” and crashing with lows 2-3 times per night. So far, I’ve had to shut off Sleep Mode every night.
I’ve read through the manual (that was a LONG read but worth it) and also past posts here, in JDRF and Reddit, but not seeing the answer yet so hoping someone here can share experience.
Here’s where I’m at right now:
The Tandem trainer had told me to set up only ONE profile in the pump with no segments. So I’ve got my basal rate set at .6 and my ISF set at 1:100 all day long
I’m on a very low carb diet so my TDD is averaging 18-22 units day.
I’ve got Sleep Mode scheduled to run from 8pm-8am. But I’m crashing hard at night (getting below 60 every night from 1-2am and again at 4-5 am).
I thought Control IQ was supposed to adjust basal to prevent lows way before they happen so not sure what’s going on here. I do see that the pump shuts off the basal for around 2 hours around those times…but I’m still crashing and the alarms are going off so I’m just shutting Sleep Mode off when the alarms wake me up.
- Let’s say I adjust my existing Personal Profile and so that daytime segment basal rate of .6 and then add a new night-time basal segment of (for example) .50 - does adjusting the night time basal rate help? To elaborate…
**What I’m confused about is: does changing the BASAL rate in my Personal Profile for night-time matter at all if I’m in “Sleep Mode” in Control IQ? In other words, does the Sleep Mode OVERRIDE the Personal Profile night-time basal setting and just (for lack of a better phrase) “do what it wants” to get me into that Sleep Mode range of 112.5-120?
- Am I perhaps turning on Sleep Mode TOO EARLY? I sleep from 10-6, so trainer advised 8am-8pm. I’m wondering if Control IQ is giving me too much too soon. When I look at t-connect, I can see that it’s upping the basal to get me into range of 112.5-120… and then I promptly crash 5 hours later. Again, is this related to the basal rate set in my personal profile, or solely due to the Sleep Mode range?
Sorry if this is obvious to everyone but I don’t quite understand how it works. Thanks much for any help!
