Mods have moved a post by @sns3guppy to its own thread here, as although it was too chatty for this low chat thread, it's an interesting post that merits its own consideration
It's different every day, but I really think fasting glucose is a poor metric and given far too much credence over better measurements such as time in range. Post-meal readings are far more significant, as are the spikes or fluctuations, rather than the absolute values. I typically see about 80-100 mg/dl in the morning, but the Libre sensor often shows low 60's. On the average, fasting, about 90ish, but my days and nights get flopped so frequently, it's really hard to say. I have zero consistency in sleep times, time zones, meal times, or medication times, as none of that is possible...
