My highest was greater than 33.6, that's as high as my meter went, with no hyper signs and the lowest or one the lowest was 1.3, at my diabetic app, and I drove(no symptoms, at all) blood sugar was 5.4, before I left for the hospital, and it raised to 2.3 after chocolate biscuit given by nurse and a couple of sips of Lucozade. Walked into consultant and he just sat their looking at me in shock as I held a fully coherent conversation with him, he then decided to refer me to be put on my local pump waiting list.As I had no signs and should have been flat on my back.
