Diabetes is not the same in everyone. Some diabetics (like my sister) are fortunate to have predictable blood sugar. Others (like me) are not. I can get low or high for no reason at all, without any change in what I eat. I can also feel low when I'm high & vice versa. I have to test immediately when I feel symptoms of either; sometimes they're the same. If I was on a jury & I started to get under 150, I'd have to get up immediately & either test or eat sugar. And I wouldn't be asking permission, either. And after I correct a low, it can take 20-30 minutes before I feel OK.
