As a type 1 diabetic, I agree with these conclusions, and I'd sum it up this way: when I have a low blood sugar, I feel anxious and want nothing more than more sugar inside me. Bouts of hypoglycemia definitely make me more impulsive. With a low enough blood sugar, time feels as if it slows down: I imagine this is linked to adrenaline... I can tell I have a high blood sugar (over 150) before checking when I feel grumpy (and bossy), I'm thirsty, and tend to have 0 appetite whatsoever.

Interestingly -- things that require long periods of concentration tend to lower my blood glucose (according to my continual glucose monitor) and stress tends to raise it.

If anyone would like to ask me any questions, I'd be glad to answer. :)
