I was 5.3 after a day spent snacking and lounging around… oh, setup a Linux box as Time Machine, and bought some records in Leamington Spa and mooched around an art festival - most of it too middle of the road for me, lots of the same old stuff, although I did like some work by a local glass artist.
Stuffed myself with potatoes, meat and veg for tea, after eating piles of chickpeas. About an hour later BG was 6.7. Decided to go for a short walk, just found the block, down to 4.3 when I got back. Felt very energetic!
