What has been your lowest blood sugar? Recently I was in Spain and mine dropped to 21 during the early morning hours. Granted I have little memory of the experience but I was pretty cut up arms legs and feet from thrashing. Numerous bruises, eye injury, very sore ribs and back. Note Barcelona paramedics had no glucose, they had to raid our fridge and the hotel lobby for sweets. This was my first crash ever and the first experience for my wife.
