That has been darn tricky to figure out. What exactly is a good serving size for me for this food for this time of day, such that i am not overstuffed and i stay satiated for a good while, ie i dont get snacky, and i can sleep at night and stay awake during the day. I feel like dam goldilocks! But mostly i have learned to wait and i wont want a second helping after all, and that has been a great lesson.
