When your blood glucose dips.... you can get very nasty effects during the long night. I get nightmares sometimes.
I use Zone nutritional bars if I can't get back to sleep, at 2am..etc. The non-chocolate ones are best for me. Zone Perfect has a nice balance of protein to carb, so as to keep insulin from spiking. I get mine at Target where they have a big selection of flavors.

There are slow carb bars at pharmacies now called Glucerna. This releases carbs very slowly and prevents dips during the night. They make liquid versions too.
You might also try Kefir... I find it makes a satisfying snack too.
