My wife’s birthday was on Saturday so we went out to eat. I had been doing fairly well in keeping my BG in check so I figured why not indulge a bit. We ate some sushi and I also had chicken teriyaki with brown rice. My blood sugar spiked to about 250 afterwards but it came back to baseline of 90-100 a couple hours later after some exercising, etc. The next day I wake up to get ready for work (4pm, I work night shift) then my blood sugar spikes again to 250?? The highest I have seen my bg rise from dawn phenomenon was about 180. Will my meal from Saturday night impact my blood sugar almost 24 hours later? This is so unfair, I already did my time for my cheat meal!

How long do you guys typically wait before deciding a sensor is bad and need replacing? My first 4 sensors with Dexcom all worked perfectly but now my last 3 sensors have all failed back to back to back. 2 of them started giving me erratic readings and 1 sensor just failed out of the blue about 3 days in. I requested a total of 3 replacements already and it looks like this new sensor will fail as well since the readings all over the place and it’s been 22 hours since I inserted it. How many replacement sensors can you request from Dexcom? Any tips on getting these sensors to work better? Should I try moving new sensor to a different location? So far I have been doing the back of my upper arm. Thank you

I would’ve been so disappointed if Team Charlie won. Glad to see Nikki and Maddy made it to the end!

I made a post about a week ago where my CGM was off by almost 50% compared to a finger prick test. I spent the last 4 days in the ER due to an unrelated trauma and I started to notice that my CGM was more accurate against the hospital’s glucometer, I assumed it was because I was now getting over that 24 hour calibration window. For example, my CGM would read 75 and the hospital test was 83 and it was pretty consistent throughout my 4 day hospital stay.
Now I’m back at home and I seem to be having an issue again. Today, I get a ton of alarms from the CGM for low blood sugar readings 55-70 but my glucometer is showing 105-110. I am using a Freestyle Libre 3 and a Freestyle Lite.

Why is my Libre 3 plus readings so far off? Multiple times today I got a warning of my bg being under 70 mg/dL and each time I did the finger prick test which came back around 115-120. Is it possible I got a bad sensor? I applied this sensor about 24 hours ago. I am newly diabetic and trying to figure this all out. Any advice is appreciated.
