Odd one

Hello,
This is whats happened today - last night went to bed on a good BG (can't remember what it was tho), then got up at 4am and tested - it was 5.1

Went back to bed - woke at just before 7am to 6.9 - not bad. I'll add .1 unit to my 4-5 and 5-6 basal. So had my usual breakfast and did my usual bolus of 8 units.

Just tested at 9.10 am as feeling a bit ropey and its 14.9!

EVERYTHING was same as normal! Woke up to normal BG, had usual breakfast and bolus.

The only thing I can think of is that when I did my BG on waking, it was rapidly on its way up and never knew.

Odd.
