Eat much lately?

I am struggling to eat my 24 points! I never thought I'd see the day when I would understand how my MIL could get away with eating so little. She can eat an orange and be good for HOURS. Yesterday I had 3 points leftover and tonight there were 8. I had to find things to eat, so I enjoyed some chips w/ queso and salsa and still had to find more to eat. By the time I ate my final point (a piece of bread) I felt absolutely full/stuffed. It makes me wonder if I missed something in my food diary.
