Personally, I'd avoid carbs for the most part. Some things I really like are,
2 String Cheeses, 8 grams of fat total and 16 grams of protein
My favorite nighttime shake is,
1 Cup Fat Free No sugar added walmart vanilla ice cream
1.5 Cups Skim Milk
2 tbsp natty peanut butter
2 Scoops choco protein powder
Enough ice to make it real thick.
Love it!
