I am now reading Diabetes Unpacked for the second time. I just noticed, in chapter 6, written by Lars-Erik Litsfieldt, he writes of his own diagnosis with Type 2 diabetes. He states

I was placed on sulfonylurea medication (Metformin.) And that his doctor said it would make sure that his pancreas would give off sufficient quantities of insulin. (paraphrasing.)

This is incorrect. Metformin is not a sulfonylurea medication, nor do they act in a similar way. Metformin has nothing to do with the release of insulin, nor can it cause a hypo, the way a suIfonylurea medication can. I know that he is Scandinavian, and possible something got translated wrong when the book was written, but this could be very misleading to a newly diagnosed diabetic who didn't know better.
