Continuous Glucose Monitor

Not sure how many of you have tried a CGM, got my doctor to prescribe a FreeStyle Libre 2. I just installed it and will post my results on Rapa day and others. Definitely feel like a lab rat :slight_smile:


The freestyle libre is pretty inaccurate, so my friend who is diabetic and gives me some of his extra sensors has told me to get a device like this below to check in the morning how far the Libre is off - so you know what is really going on. You can’t adjust/calibrate the Libre 2 directly. In my experience the Libre is typically 15 to 30 points higher than the finger prick glucose measure.


Thank you @RapAdmin. I may do some backup testing. I have a good friend who has a daughter with type 1 she uses the Dexacom g6 as her daily driver but has used the Libre 2 before and found it okay. He suggested I use it for value and since I am only looking for directional readings. I am not taking insulin after all.

I have taken a few ratings thus far. 101, 92, 106. All pretty low.

I have tried the Dexcom G6 and more recently the G7. The G7 did fall off, but Dexcom sent another. I will run a Dexcom session again soon, but I want to plan things around that.

generally carb tolerance goes way down on rapa days

Interesting drop post Rapa and exercise to 60s. Fun to watch this.

One important thing to know about the Libre2: the current “reading” and trend line for the last 20 minutes is a model. It takes 20 minutes for the sensor to finalize a reading, so when your glucose is changing, I find it tends to over shoot.

You’ll notice that the next time you go to scan the last 20 minutes of the previous scan will be gone.

I also highly recommend upgrading to the Libre3, as it does not require scanning. It streams to the phone and is smaller.

Is that something you have personally experienced by measuring it?

yes, when wearing a monitor, I saw much larger then normal spikes in the 48 hours post rapa (7 mg at the time of rapamune)

Interesting. Thanks for the info.
