drink your milk only after you eat solid food.
ever woken up, drank 1L of milk and felt full well into midday? try having your eggs/whatever for breakfast, then downing the milk.
Also, eat foods you really really like. novice phase is more about quantity of food rather than quality, and that focus will switch the other way when you enter intermediate phase because your body won't be as big of a nutrient sponge as it was when you first started.
Trial my suggestion for 3 days, see how you go. best of luck
