A) Milk is good, but don't depend on it for a protein source. You're trying to utilize it too much. 1-2 glasses a day, fine. Trying to use it with every meal, not the best.

B) Carbohydrates are your friend. Sure, you're getting some from the milk, but that's not the best primary carb source. Neither is the bread with your sandwiches. But at the same rate, don't think that carbs are a 'free' thing.

C) Try to take in mostly unprocessed, whole foods.

D) Most likely, you need to up your cals.

E) Man up and eat some veggies too.

F) Vitamins? EFA's?

And btw, what's your weight? What are your calorie and macros levels per day? If you know, that is... which if you don't, you need to learn to do that.
