Considering using a CGM to assist with my health journey, and Lingo seems to be both the most consistent and more affordable option. I've done the doom scrolling searching for reviews, but it's hard to sift through the junk that inevitably crowds out any actual human experiences. So-- going to try just asking. Has anyone here actually used the Lingo CGM, just to get an idea of blood sugar spikes and the relationship with different foods and exercise on blood sugar, and what was your experience? Probably not going to use it long term, but currently considering the 12pk/6 month option. Thanks!

First time using a CGM and not a big fan of needles, but I’m used to using the finger sticker. Unit failed during warmup after three minutes. Is this a common occurrence? If it is, I think I might pass.

Earlier this year, my A1c came back at 5.7%.

I’d heard “walk after meals” for years—from my parents and from doctors. I knew it was good advice, but it never really changed my behavior.

Then I wore a CGM for two weeks.

My breakfast is usually the same: oatmeal, milk, and protein powder. I compared days when I took a 10–15 minute walk after breakfast with days when I didn’t.

Blue = 10–15 minute walk within 30 minutes after breakfast. Orange = no walk.

In my small dataset, the average rise from pre-meal glucose to peak was:

• No walk: +34 mg/dL
• 10–15 min walk: +22 mg/dL

Not a controlled experiment, of course, and CGMs aren’t perfectly accurate. But seeing the difference in my own glucose changed my behavior in a way generic advice never did.

Now I walk after breakfast almost automatically. I don’t need a goal, reminder, or much willpower anymore.

That was probably the biggest thing I learned from using a CGM: the data made an abstract health recommendation feel concrete and personal.

It also made me start thinking in small experiments instead of trying to overhaul everything at once: walk after a meal, change a portion size, compare different foods, and see what actually matters for me.

I documented the full two-week experiment here:

For those of you using a CGM: did seeing your own data actually change any of your habits?

Does anyone have a discount code I can use? They are limited to 20 uses I think, so any code that’s been posted here for more than a fee hours doesn’t work anymore.

So I recently switched to Dexcom and I noticed wayyyyy more highs than on the libre. On the libre my glucose was always going below 70 and never above 145. With the Dexcom it’s never below 80 and spikes to like 180. Neither of them seem to be accurate to my finger sticks. I’ve only tried them on the backs of my arms. Does anyone have any recommendations for a better cgm or maybe a better placement? I’m so tired of not having accurate results. (I don’t have diabetes, I monitor glucose because of gastroparesis) TIA!!!!

The peak increase ranged from only +23 mg/dL to +68 mg/dL.

Here are glucose peak increases for these meals:

• Chicken + chickpeas + cabbage + pistachios: +23
• Instant noodles + fish/eggs/vegetables: +31–41
• Chicken nuggets + apple: +60
• Pasta + beef: +68

The pasta surprised me the most. I had assumed that if the carb counts were similar, the glucose responses would at least be somewhat similar.

After looking at my CGM data, I’m starting to think of carb count as more of a starting point than a prediction. The type of carbs and what I eat with them seem to matter a lot.

I plotted the full CGM curves and explained the comparison here if anyone is interested: https://youtu.be/mArqUz1480U

I’ve been wearing a CGM since May and I’ve lost 20 pounds..
I check my weight every morning.

I used intermittent fasting while avoiding glucose spikes and drops.

I decided to finally take it off and try without it for a little and I’ve gained 5 pounds…

I have been eating guilt free the last week, with no immediate numbers that show me my glucose I have been overeating…

I ended up putting a new one on this afternoon…

Ready to get back on the wagon.

Has anyone else had weight gain after taking off their continuous glucose monitor?

I’m really interested in Eversense, but even if I can get a doctor to prescribe it, the cash price looks pretty rough.

Has anyone here paid out of pocket for one? What did it actually cost?

I also don’t really understand why a CGM needs a prescription. If I know insurance won’t cover it and I’m willing to pay for it myself, why can’t I just buy one?

I wore 2 Stelos and 2 Lingos simultaneously for this experiment (using 2 iPhones) Because of sensors and cloud service issues, I was only able to get ~1 week of overlap between all 4 sensors.

At some points, the glucose values between CGMs were 77 mg/dL apart!

But if you ignore the differences in absolute values, the shape of the trends and spikes are pretty similar. My takeaway is that we should not be paying attention to how much time we are in the healthy 140-70 range (because sometimes a sensor said I was high while the 3 other sensors said I was in range), but rather look at how many steep spikes we have.

I also have finger stick, Oura ring sleep data, activity and food logs, which I plan to overlay on this graph.
I plan to make the data and python code (JupyterLab notebook) available if anyone is interested in doing more analysis or checking my work.

Das ist mein erster Freestyle Libre 3 Plus - Sensor. Er soll mich vorm Unterzuckern warnen.
In den ersten 48 Stunden lag er konsequent genau 20 Punkte über dem tatsächlichen Blutzuckerwert. Doof, aber nicht so schlimm - kann man ja entsprechend einstellen. Jetzt, seit dem dritten Tag, sind die Messungen völlig unberechenbar: Mal weicht er um 16 ab, mal um 12, dann um 5, dann mal um 7. So bringt das nicht viel. Ist das immer so?

why are CGMs so expensive 😢

The new Stelo app is terrible and almost unusable. It is difficult for me to see my glucose levels and the graph totally disappears when I’m not wearing a sensor. So that means I can’t see full historical data, only a summary.

Most of the app is now coaching and insights. I just want to see my glucose levels!

I tried to post in the Stelo channel but it seems to be locked down. Are there any Stelo users here? How can I get the old app back?
