Hi
@Scott78
First things first, are you testing for ketones, either with the blood or urine strips? If your levels are persistently that high, this is is important.
If you are negative for ketones, then I would be tempted to ring 111 and see what they say. If you are positive for ketones, get yourself back to A&E asap.
Also, don't panic. I know this sounds really scary, but panic will just drive your sugar levels higher. Keep testing, both sugars and ketones.
Are you on fixed doses or are you carb counting? Do you feel confident in applying correction doses?
