I nearly died in my sleep 2 years ago from about 10 units unexpectedly releasing into my system from swollen tissue left behind by a broken infusion site. What the author describes is potentially lethal. The thing is, there is no such thing as a lethal dose of insulin per se. If you want to eat half a large pizza and wash it down with a can of coke, you'll likely dose 15 or more units. But dose the same amount and end up not eating your meal and you are in extremely big trouble within half an hour.
