Don't feel full....

I am 1 day shy of 1 week post-op. I have been drinking my 64 + fl oz liquids and trying to keep on a 3 meal-a-day schedule, but I don't feel full. In fact my tummy growls at me all the time. I really don't feel any restriction at all, but I am really unsure if I am filling my pouch. If I eat a jar of baby food, is that too much or not enough? I haven't changed in the way I drink any of my liquids and don't feel that I am drinking too fast. Is this normal?

Me 3/13 I could drink as much as I wanted almost as fast as I wanted. I drank three protein drinks a day around meal time and drank water the rest of the time. I made the drinks with 6 oz water and powder. I did not have any appetite. Just counted ozs and grams. I started the full liquid phase today and went to McAllister's Deli and ordered a cup of potato soup. I picked all the good stuff off the top and wiped on the soup. I ate slow and was full on a little less than half. I just ate a stallone pudding for dinner at 7:00pm. My doc is conservative I have assumed from reading psots and I don't start purred untill week 4. Be strong and positive--bj
