I had a mini mince pie, well 2 in fact, this evening with no insulin. At 10 I checked by BG and it was 18.5 so I took 7 units of novorapid. 2 hours later it's still 15.5. I haven't eaten anything for at least 3 hours. Anybody have any reasons why this is. My Bgs have been below 10 for last few days.
