After deciding that he wasn't really diabetic and indulging himself to several days of tons of mashed potatoes, pasta, sugary soft drinks, etc, he finally got consecutive blood glucose readings of 138 and 139. That's high, for him. So it was back to earth again. Now he knows he can't just eat whatever he wants, in whatever amount he wants. But I think he realizes too that with just a few tweaks of his behavior, he can keep this nasty stuff in check, so maybe it wasn't such a bad lesson.
