Hi Daphne, Thank you for replying!
I don't think so, but I fit the profile for T2 so I am assuming the GP has made the call. He's happy for me to try to bring my numbers down on diet alone for 2 or 3 months. (First HbAc1 was 89, second a fortnight later was 77; at this point I'd been low carb for 3 weeks.)
In the last couple of days since I posted this, I've still been having daytime readings of 11-13, seemingly whatever I do or don't eat. Maybe it'll just take a good deal longer before I see any changes? It just puzzled me that the readings were rising even if I hadn't eaten anything, and that I was feeling so bad.
