Interesting. I would think that it would be dangerous administering insulin at night, especially regular, since the person would be asleep and possibly unaware of any precipitious drops (Somogyi effect). However, if the glucose levels are high, you wouldn't want to drop it too drastically, so I guess you could either give a longer acting insulin that would peak during waking hours, or a smaller dose that would bring it down gradually. I guess I should have instead said "I would think that the norm for diabetics would not be to wake up in the middle of the night to receive insulin".
I think that's certainly true. I've had a heck of a time controlling my waking sugars, for years in fact.
bigsigh, to answer your question I have heard of those inhalers, and assume they'll be out soon. I wish they would commercialize a blood-sugar testing device that doesn't require sticking. I heard they have one, but it's extremely expensive.
