When I started calorie counting in the beginning of March, I would make a rough plan of my eating for the day so that I wouldn't a) run out of calories before dinner and b) end up with 800 left at 8pm! Maybe that would work for you? I plan for breakfast, snack, lunch, snack and dinner each day.
I also add a piece of wheat toast with peanut or almond butter, or a glass of low fat milk when I need to up my calories.
