Bro, take casein before you go to bed , because it is slower releasing and will release into the bloodstream slower than whey. Whey is perfect for when you wake up in the morning, and post workout, as it gets to your muscles fast. Be sure to eat another complete meal within 1-2 hours after the whey shake to keep yourself anabolic.

Good luck, and don't be too hard on yourself, your english is better than mine, and that is my first language!
