After being diabetic for 20+ years I had my first, full on Hypo last week and it scared the bejesus out of me. I got up in the morning, did my normal blood test and it was 5.1, which is pretty low but was because I forgot to eat an evening meal the day before and I've had it in the low 4's before without any issues. So I took my meds, including my insulin and then had three pieces of toast & jam and milky coffee for breakfast, thinking that would sort it out. However, I think I must have accidentally injected the insulin into a blood vessel because my blood sugar crashed by the time I'd finished my breakfast. Headache, hands shaking, crazy sweats, extreme tiredness, my eyesight went really blurry and I felt absolutely dreadful. So I chewed four glucose lozenges, had another three rounds of jam & toast and a glass of milk and then had went and sat in my recliner as I was feeling so shaky. I woke up (thankfully) eight hours later, at which point I was feeling fine.
