I’m on about day 5 of the CGM trials. I’ve spent 80% of the time asking what I’ve gotten myself into. (And I’m really happy my insurance covered this outright, because I’d be pretty pissed off otherwise.)
I can’t seem to calibrate this thing to work properly. I know you are supposed to to wait until there isn’t any active insulin or when there aren’t huge drops or spikes. The problem is that I am always snacking on many small meals during the day, so there is ALWAYS active insulin. My other problem is the low blood sugars – which force me to eat and rebound making calibration impossible.
This makes it hard to see what my blood sugars actually are. When this photo was taken, my blood sugars via fingerstick had already dropped to 206 mg/dl. Not ideal, but most certainly not nearly 300 and rising.
I’m finding that the CGM is two steps behind or one step ahead. If I treat a low, my blood sugar starts to rise within twenty minutes. However, I still end up fighting alarms for the next 30 minutes. I’ve also seen steady lines in the 130 range for a number of hours, while my fingersticks say I’m 177 or higher. HUGE discrepancy.
The low blood sugar alarms woke me up at least 5 times last night, which isn’t something I want to happen when “springing forward.” My sensor alarmed nearly every half hour for 3 hours straight. I treated non-lows at least twice to get it to shut up. (The lowest my meter recorded was 77… while my sensor said 58.) I woke up to a 155 vs. 123 discrepancy again.
I know I can safely maintain the sensor in for 6 days. I’m about ready to chuck this sensor and start over.
This isn’t what I wanted. What am I doing wrong y’all?
