Blood Sugar

What is the best snack / food to keep blood Sugar leveled throughout the night? Something that will keep Sugar levels nice and happy. I have candida too but am trying to get something to eat before bed that I know will keep my blood Sugar super happy. I'm doing a lot of research and it looks like vivid dreams and some of the wakeing I'm experiencing is from blood sugar dropping.

I tried protein shake, but that didn't work. :-)
