I would ring the 24/7 NHS line, but I would also Take a first dose correction, till you are further advised
going by the sickday, you correct now at 20% daily dose every 2 hr and bolus for your meal when you have it, it seems to be a bonus that you haven't ketones
"If bg is over 13mmol/l and ketones are “moderate” or “large”
Calculate the total insulin (basal and bolus) in the previous 24 hours, calculate 20 per cent of that.
Bolus: take equivalent of 20 per cent of that daily total every 2 hours
Plus normal bolus ratio for anything you eat.
Maintain usual basal doses
Monitor bg and ketones 2 hourly.
Have 100ml of sugar-free liquids per hour.
When bg drops below 10mmol/l AND ketones are negative or trace:
Eat/drink 10-20g carb
Use normal bolus ratios
Use normal basal dose.
Monitor bg and ketones 2-4 hourly.":
