Good idea. Also, for a "full-up" feeling, think fiber!
I have found in these last few days that if I drink a small glass of skim milk, and pair it with some oatmeal (with splenda, or if you prefer more natural,honey for sweetness) and maybe half a banana, I can feel fuller a bit longer. With everything I have, I try to eat protein (like lean lunch meat, a boiled egg, some type of beans, etc.) and something bulky (like oatmeal,bran,popcorn,etc.)
