Once you get to more solid food, even mushies you'll feel restriction. Be grateful that you aren't struggling with protein and fluids, and that you can get those vital fluids in so early out. That will definitely help you recover. As for hunger, that nasty Ghrelin hormone is still in your system. It's a hormone and has to work it's way out. Plus, it's a liquids in, liquids out kind of thing. You're brain is still working with all the hunger hormones, signals, scent of food etc etc, it doesn't really know you've had a portion of your stomach amputated so it is confused as well. Give it all some time, and you'll get restriction once you get to more solid foods. That's when measuring becomes really important so you don't overeat and cause discomfort.
