This bedtime snack has been working for me (my morning sugar levels are pretty good, in the 70s/80s), so I thought I'd share.
I've been mixing about 2 tsps of malt/chocolate ovaltine with skim milk, and warming in the microwave. Sometimes I'll top it with whipped cream (which is only 1 carb). The milk is about 13 carbs, and the ovaltine is 4 or so (I don't use the full serving size). So, it ends up being about 17-18 carbs total and you get a good amt of protein too from the milk.
Re: sweet bedtime snack idea for GD ladies
This sounds yummy! I do something similar and make a Carnation Instant Breakfast Shake with skim milk for 24 carbs. I'm not sure if you could warm it up, I suppose you could.
Brown sugar oatmeal is another one, it ends up being about 45 carbs which works well for me because I need something bigger for my night time snack to keep my fasting number down.
Have you tried some popcorn with cheese or almonds? That's another one of my bedtime snacks, if I want something savory. I can't do crackers at night, but I can do diary (wierd!).
