Finger prick for ketones is great, as that's the most urgent worry!I’m super thirsty and my mouth is almost always dry.
Diabetic nurse just called back and made an appt to see me tomorrow at 12.30. She mentioned glicazide to bring them down straight away. She said she would do a finger prick to test for ketones and go from there.
I'd ask for a referral to hospital as well, because you're seeing such high numbers while the only carbs you've had really was the milk in your tea. The Gliclazide may be helpful, they brought me down to low teens instead of high teens for a while.
