To Eat Or Not To Eat

I will be three weeks post op on Wednesday and I am currently on mushies. I am finding that I really am not hungry and small amounts of food are filling me up. But the problem is trying to determine if and when to eat. I usually would follow the breakfast, lunch, afternoon snack and dinner schedule. My doc did tell me if I am not hungry, do not force myself to eat and that it the exact opposite of what I have learned in the past. I would eat a little something, even if I was not that hungry to keep my body going. Now I am eating whenever I get a twinge of being hungry. Today I had a protein shake around 1pm because I was still pretty full from my dinner the night before. I had a scrambled egg later and then a container of greek yogurt. I also drank water all day. I am full now and probably will not eat much else today. Is this normal? I have my first fill in a little over a week and I am thinking I will bring it up then.

On a sidenote, I am down 3.2 pounds today and I am very happy about that!!!
