Yep, when I was about 10/11 I got so low.. (Back in the days of vague pee tests before personal meters.) that I was throwing spasms in my numb legs..
Pale, sweaty & "goosesteppimg" my way past visiting relatives at the time with my focus on the kitchen. They must have thought it was a zombie outbreak!
Thinking about it? I was surprised I could barely walk.. I never let it happen again. (But then, the old bovine insulin was always a killer with the hypo symptoms for me.)
