I had been a bit stressed during the evening. The reason for my late arrival home had been a 4 hour wait in A+E with my partner, although everything turned out to be fine. I was quite prepared for the test I first did when I got home to be higher because of it, but it was a very normal 4.7. I did another test about an hour after the 8 just before I went to bed and I had dropped to 6.7. Woke up about 3 hours later and so did another test and I was down at 5. Not sure why I had the spike considering that I had twice as much bread at lunchtime along with a bunch of other stuff. Maybe I had eaten so little, that my pancreas just didn't realise it was supposed to do anything.
