Thank you for posting this blog.
I recently saw a news report on the suspected link between high blood sugar levels and memory loss, and am not all surprised by the conclusion. I'm a Type II, non-insulin dependent diabetic, and find myself much more alert, energetic and generally capable when my blood sugar is well-controlled. I think regular and vigorous exercise makes a big difference for me in this respect, though its hard to be certain it is actually the exercise and not the power of expectation that makes me feel better. Either way, though, I've become a gym rat and go through mild withdrawal if I miss a day.
Hoping your blood sugar levels stay lower than my golf scores,
