Sadly it wasn't the meter or anything on my hands. The 14.7 was an hour ago, I took a correction and just tested again - 12.5. Another correction.
I also have the mother of all headaches.
When I got up at 8am my BG was 4.0 but I was feeling okay so just had brekkie and let the pump correct (i.e. give me less insulin for the carbs).
Maybe it's a delayed liver dump? Is that possible, 5 hours later?
Feeling pretty poo, anyway. And I was having such a good week!
