I had the same and gave up finger 5s 6s and Libre 15s 10s off the scale. Drove me nuts with a sore arm and really down thinking I was a failure. Just not for me.Here I have a bit of a dilemma.
Trying Libre. This morning it read 9.3!!A quick check with two different meters and strips from different batches gave 6.1 and 6.0.
Throughout the day Libre showed 8s, meters 5s. Also ketostix showing nicely into ketosis. Binned Libre, as it was hurting arm and getting in the way.Never again. Going to stick to finger stabbing. With a bit of sulking thrown in for good measure.
