I'm starting to become conscious of this. 2 days ago I began to stuff myself by trying to finish my side dish at a restaurant, even though I was full. When I realized what I was doing I asked the waitress for a box to take it home.
There have been times when I've eaten after I was full because I didn't want to waste food, or I felt like I would be wasting the money I paid for the food. I'm learning that it's ok to eat it later or not at all.
