@logindetails - Are you mega-muscle-bound or something? The only other, you-specific" factor I might wonder would be if the beer made you a bit de-hydrated and just pushed you over the sensor's working threshold.
I must admit, the revelation you had is the sort of data I would love. I'm a non-medicated T2, running very low numbers, and an HBa1c of 32. I rarely see numbers higher than the odd 5.2, but to achieve an HbA1c of 32 (5.1%), I clearly must be running higher sometimes. Obviously, I would have limited options to manage those peaks, even if I wanted to (or if they were few, but horrendous), but it would be good to know.
Once things settle with the product, I'm likely to have a starter pack, then a periodic sensory; probably just before I have bloods done.
It's an exciting development, for sure.
