Costco prescription

Just had my 90 day prescription sent over to Costco for the first time - in the app the price shows as over $600 - am I right to assume they'll add discounts in-store to bring it down? I'm paying cash price even though I have insurance because capitalism...

My insurance has decided I can no longer have Libre so I tried to get their preferred Dexcom at my usual pharmacy and it was 3x the price I'd been paying for Libre - don't understand why they have a preference if I'm effectively paying the cash price anyway but whatever lol.

Can someone explain compression lows? New to CGMs (and diabetes)

Hi all! I’m new to diabetes and we don’t even know what type I have yet (but it type 3c looks like the main suspect). I have looked online for this info, but don’t understand ‘compression lows’.

The online info says compression lows are a V-shape. My graph shows a more gradual decline, but sharply improves after I woke up feeling godawful (without sugar).

What ways can I differentiate between a compression low and a low-low?

Drastic reading difference between CGM and glucose monitor.

This is a brand new CGM (Freestyle Libre 3+). It's reading super low but a finger stick is showing it off by over 100 points. The last one I got did the same thing over the last 4 days. Is the date on the packaging the production date or the product expiration date? It read 8/13/2026. Is there anything that can be done to correct this huge discrepancy or should I call the manufacturer and ask for a new replacement?

My free macOS app, Glucose Please, now also supports Freestyle Libre

Glucose Please is a free macOS menu bar app that lets you see your CGM readings at a glance while you’re using your Mac.

It started with Dexcom support, and I’ve now added FreeStyle Libre through LibreLinkUp.

You can see your current glucose and trend arrow directly in the menu bar, then click to open your recent glucose graph. There are also customisable high and low alerts, support for mmol/L and mg/dL, and Insights to help you explore your glucose patterns over time.

You can optionally save your glucose history locally. Saved readings stay encrypted on your Mac and aren’t uploaded or synced elsewhere.

For Libre, you’ll need your readings available in LibreLinkUp, then you can sign in with those credentials in Glucose Please.

Download and setup instructions: https://glucose-please.app

If you give it a try, I’d love to hear how you find it. Feedback and suggestions are very welcome!

Too Far Off Too Often

Different Days, Different Times. Just too inaccurate. Constantly.

When I got on the First Freestyle Libre 3, It did help me see the errors of my eating ways. With just a meter, I was missing many of my extreme highs. I NEVER went too low. So for that, I am thankful.

But NOW, while I am in more control, this thing is a piece of JUNK. I don't know if the hardware changed, the software changed or it's all not too great at lower numbers.

It is CONSTANTLY off. And it's not just ONE sensor. Then at time, it will be close. I cannot trust the readings. It goes LOW quite a bit, and when I check the numbers with meters, it's not even close. And Abbott and the Government seem to not care. I know +- 20% is suppose to be acceptable, but this IS ridiculous.

Even worse is when I leave my house. I rarely lose connection when I am at home. Like once every few months. BUT, if I have to go out ANYWHERE, I get the alarm for NOT CONNECTED. It's bad enough the alarm goes off, I have to get the phone out and ACKNOWLEDGE IT. But 10 minutes later the Alarm Goes off AGAIN.

What I REALLY hate, is when the alarm goes off again it TURNS THE VOLUME UP AGAIN TOO. I got the alarm, fine, You suck when we are out in the REAL world where other signals can interfere, even though the phone and sensor are rarely more than 3 feet apart. But to CONSTANTLY increase the VOLUME and go off without the ability to disable it or control the volume is STUPID and ANNOYING. Especially when I am in a business meeting.

There's NO WAY to disable that unless you uninstall the software.

I have 3 months more of this junk. I've had enough. I plan to give Dexcom a shot.

Libre 3 plus constant inaccurate lows

This is happening more and more. Constant inaccurate lows. When it showed I was at 54, I did a blood stick and was 105.

u/smiles_mmm — 13 days ago

This thing drives me insane

First of all: this photo is inaccurate as hell. It has beeped at me for being “below 55” way more than this in the last 14 days. Today it’s done it four times alone.

It woke me up twice last night alone. Today I ate some lifesaver gummies (like half a bag, work has been a damn time). Half an hour later I’m apparently dying and below 55. No, no I am not.

An hour and a half ago, I’m eating dinner. A bowl of pasta. Apparently I’m below 55. No, no I am not. I had a jello and tapioca pudding for dessert. Just now I’m apparently below 55 again. No, no I am not.

Night before last it woke me up twice. Sensor before this, same thing. I am so sick of this thing. I used the first Libre years ago and HATED IT for constantly being inaccurate. I switched to the Medtronic Guardian. Was it bulky? Yeah. Did I have to calibrate every 12 hours? Sure. Did I have to change it once a week? Yup.

But was it always accurate and actually do the damn thing it’s supposed to? Yes. I will NEVER forgive Medtronic for discontinuing the product. Ever. Now they have a new one where you HAVE to be insulin dependent and use their stupid insulin pen to get it. I have boxes of old sensors and they just… discontinued the app and sensors. I hate them so much. They had 24/7 support and everything. And the new Dexcoms are just as bad as the Libre 3s with inaccuracy.

I’m tired. These last two sensors weren’t even from the same batch. It is 2026. Why can’t this crap just WORK? Does anyone else have these issues? 😭😭😭

Are these false alarms? Is the Libre 3 really showing false dips in blood glucose?

I am not sure what to do now. I purchased a FreeStyle Libre 3 sensor and blood glucose strips because I had a suspicion that I might have nocturnal hypoglycemia. I have been battling horrible symptoms for over a year with acute episodes of dizziness and faintness and shakiness followed by severe brain fog, and no doctor has been able to help me. So I am playing detective, trying different things myself. The lab has previously flagged my average blood glucose over a three-month period as too low. Consequently, my doctors asked whether I am eating enough, and I am! I have even gained several kilograms.

When I put the Libre 3 on, everything was fine. It did not hurt and connected fast to my phone, but already after a couple of hours, the alarm just started going off pretty often. I was at a friend's house and hadn't eaten in several hours. I was feeling very dizzy, so I said to myself that this might be something indeed.

Now 48 hours have passed and the alarm goes off very often, like once an hour at least if I haven't eaten in 2-3 hours. At night it happens a lot, and I have drops as low as 3.0 mmol/L (54 mg/dL). And no, I am not compressing it, as I am sleeping on my other side. Last night I was awake from 1 AM to 5 AM with horrible symptoms… the alarm went off again and again. Usually eating puts me back to sleep, but I refused to eat because I really wanted to catch these episodes, so when I saw the graphs, I had lots of dips in my blood glucose. I thought, this must be it... my symptoms are caused by some kind of non-diabetic hypoglycemia. I almost cried because I thought, "Finally, I have some answers."

So today I started using the strips to confirm these drops, but the results are all over the place and don't really match my Libre sensor. The Libre sensor seems very stable and has logical trends; it goes up when eating pretty fast and correlates with my symptoms also when I have the dips... but it's consistently lower than my actual blood glucose levels. Sometimes the difference is small, like 0.4 mmol/L, other times it's a bigger discrepancy. I am very frustrated... as I am highly symptomatic and I can feel the episodes before the alarm goes off, but it doesn't matter if the blood glucose device shows totally normal glycemic levels... I wanna cry.

Four failed Libre 3 sensors in 48 hours

I just need to rant about how much I hate this product. The first one stops working after 3 days. I finally replace it after it doesn't start again overnight. Two hours later I brush against a doorframe and it pops off. I try to put on a third but blood gushes out when I put it on and it won't stick. I put on my final one and it stops working after a few hours.

A product this important to a diabetic's health cannot be this piss poor and prone to failure, especially with how much the greedy assholes at Abbott charge for them. I want to switch so badly to another CGM but this is the only one my insurance will cover. I'm calling them tomorrow. I've gotten single replacements before but never this many at one time so we'll see how that goes. Then going to my endo to see if they can fight my insurance to cover another CGM so I can be done with this.

Possible gestational diabetes

Hello every one. I wasn’t able to finish my three hour glucose test because I had thrown up halfway through my test. Instead of making me retry it, my doctor got me on a CGM, specifically freestyle libre 3 plus to monitor sugar for a couple weeks. My meter constantly is telling me 70-85 sugar range all day. Whenever I eat, it will go up to around almost 130 at one hour later and then it goes back down to 70-85. I was not sure if my meter is messed up and running low, or if this is normal? My blood sticks are always <120 an hour after meal when I check it too double check but I am not sure. Is it normal for blood sugar to do that if you don’t have diabetes? I guess I just imagined it would be higher and maybe for longer. I just don’t know if my meter is messed up or if maybe I don’t have gestational diabetes and this is just what normal blood sugar does. I just get so nervous I want my numbers I report to be accurate so I don’t hurt my baby on accident :(

Hype me up lol

Hype me up to put on a new sensor lol. I took a couple days off because my last sensor was amazing to start but then started falling off and was reading CONSTANTLY under 54 sending me the obnoxious loud alarms when most of the time I wasn’t even actually low at all or at least not that low so I honestly just got tired of all the alarms and questioning the thing.

I did my stomach the last 2 times and it’s by far the most accurate but the first one got itchy after a couple days and I accidentally ripped it off in my sleep forgetting it was there and going to itch it. And the 2nd obviously like I said was great until it REALLY wasn’t lol. The 2 before that I don’t think worked at all if I remember correctly, they were arm sites.

Probably gonna try the stomach again. I’ve started a full time job recently so it is indeed important for me to put it on again cause it’s harder to track and manage at work without.

4th Libre 3 Plus - Can someone give me insight??

1st: It fell off from hitting a doorway after 3-4 days, but it had been reading very low the entire time. It was 30-40+ lower than a finger prick reading.

2nd: I replaced the 1st one with a second one on my other arm, and it actually read well! but then it died after about 5-6 days; I also accidentally snagged it & I think it came loose.

3rd: My third one I put on last night without having one for a week. This is the first screenshot. It barely read and immediately went downhill. I went to sleep & woke up to it saying there was a sensor error & had a pop-up for me to file for a replacement. I can’t remember exactly what it said, but I told myself I’d handle it in the am. When I woke up, it had disconnected & I couldn’t even get the serial number. I tried to reconnect it, but it wouldn’t allow me.

4th: This is the second screenshot. I put this one on this morning, and it’s been reading consistently low all day and is 50+ off of a blood reading.

I’m really not sure what I’m doing wrong to have 3/4 read so inaccurately or just die… any ideas or other people experience the same thing? The one that worked was really nice because I could even go back and log what I was at if I missed my 2 hour mark for my gestational diabetes tracking… I just really don’t want to continue to finger-prick 4 times a day.
