before bed take a fish oil pill and nothing else but some water. this will prevent muscle tissue loss, and promote fat burning while you sleep. if you have a really fast metabolism take some amino acids with the fish oil.. nightime is for fat loss!
Fish oil by itself won't do shit to prevent muscle catabolism. Get in some whole food sources like lean steak, salmon, or a couple tablespoons of natural peanut butter. Your body still needs the calories to keep from eating up muscle.
As for the Muscle Milk, like somebody else said, they're decent on occasion but not the best choice for a regular meal. It'd be one thing if they had fewer carbs, but a high-fat/moderately high-carb drink isn't ideal.
