OK, I'll admit it. It's a little too early to have a love/hate relationship with my CGM. I'm excited to be hooked up (literally, it is IN me) and I am not upset that I have to have another thing in my body 24/7, but I just don't know what to think of it yet. It has already failed, and it's been only TWO days. I'm not really sure what happened, but it predicted that I was going low with 1 arrow down and a 90 BG. I checked my # and meter read 130. I thought maybe something was wrong because I had turned down my basal and just ate a small snack, so it shouldn't be heading down...so I calibrated and shortly after, I got a calibration error. Say whaaaaaaaat?! I did what it told me to do, and then it went back to "warming up" mode, and then told me to "change sensor." I called my CDE and she told me that when I calibrated during a down arrow, it knew it wasn't on target and that may be a reason for why it failed. That seems weird to me! But now I have to change it after only 2 days and I am a little nervous about it. She helped me do it the first time, and it was mostly her doing it because I always feel so awkward with all the little steps. I was that way with my first pump change though and now it's like second nature, so I know it won't be a big deal...but I also don't SEE the needle going in me with a pump change. The needle with the CGM is a little intimidating!
I don't have too many thoughts on my CGM yet...I know that I need to give it time and it's mostly for trending, but I still don't know what to do with that info yet. Except for this reading today, it's been right when I was heading down or heading up, and knowing that has been a comfort and a relief. Sometimes the readings were within 5-20 points, and sometimes they were 40-60 points off. A couple times they were 100 points off! Sometimes the CGM showed me I was doing better than what my meter showed, and sometimes it showed me doing worse. I also wasn't sure if the calibrating was helping it figure things out. I know they said being within 20 pts is great, but it can be such a big difference! Being 40+ pts off was really frustrating, especially when it showed me a worse # than the BG test. If I want to see the up and down graph of my levels, I don't want to see a 180 on the graph when I'm really a 140. That's a big difference! However, I also remember reading that the sensor takes time to catch up to the actual BG reading. With all the high-tech stuff out there, I'm not sure why this hasn't been figured out yet. I know it only reaches your interstitial fluid and that's one reason for not being completely accurate. I guess it's just slightly disappointing and frustrating, even though I know it's used mostly for trending and spotting patterns. But if it's off 40+ points, what are you supposed to do with that?!
I am already missing it a bit though, now that I need to replace it with a new one. I like getting an idea of what's going on inside my body. Also, I'm slightly obsessed with it. I've been looking at it constantly! I find it really fascinating, even if it isn't always accurate. I'm hoping that the next sensor will go more smoothly and as time passes, I will know what to do with all this info. Also, I definitely need to brush up on my pumping skills. Meeting with my CDE made me realize there are certain features I wasn't taking advantage of, and I know I really should re-educate myself.
And yes, you do have to charge the transmitter. But it only takes about 10 minutes.
