old thread! lol, it's cool though.
IMO, you always need to eat before bed. If you are bulking, use some complex carbs with casein proetin mixed with 1% milk. If you are cutting, casein protein mixed with water. I use 50 grams casein and 15 grams of whey isolate. Keep the amino levels in your blood up to prevent and catabolism.
Whey only is better than nothing, but hardly ideal.
6 ounces of a light fish (tilapia, halibut, orange roughy) also works fantastic if you don't mind having nasty farts in the morning, lol.
