Diabetics, Lets say before you go to bed, your blood sugar is to high, so you take just a little insulin to correct it, but you take one or 2 units to much. Than you go to bed. And durring the night your blood sugar dips to the point where you get that miserable shakey feeling.

The question here is, can just one or 2 units to much insulin kill you unless you ate a piece of candy or something,
or

if you took no action, would you be able to recover on your own and have nothing more than your body get shaky and miserable for a while.
