How many times do you eat a day? If you split up you food intake into 6-7 meals a day spaced every 3 hours then you should be able to hit a high your caloric intake pretty easy. Also remember that your body can only use so much food at one time so if your shoveling in high calorie/protien foods all in one setting, it's likely your body isnt gonna use 20-30% of it and just shit it out. And if your ON, like Nate said wake up and have some food. Shit when I'm hitting it really hard I'll set an alarm for 3am and get up and eat a bowl of oatmeal and drink a shake, plus I keep muscle milk bars on my bed stand if I'm to tired. I fell asleep back asleep with one in my mouth a few weeks ago and ended up with chocolate on my pillow.

Steak, chicken, fish, sweet potatoes, broccoli, oatmeal and eggs are what I consume for the most part on a regular basis...protein shakes with every meal, before and after workouts, and casein before bed. Also if I wake up in the middle of the night, I might down one real quick... That's when I'm ON, when I'm not ON, I eat the same but drink a lot less shakes. I utilize quality food for protein and carb intake, and use shakes to up calorie intake when needed. The majority of my nutrition comes from real food, not shakes. Shakes are just an accessory of a diet, and shouldn't be relied upon heavily as a necessity
