you'll likely start feeling the restriction once you move to solid foods. I didn't feel it at first, either. Like Arabesque said, it takes some time for the nerves to regenerate, and also, you're not on solid foods yet.

At 3 weeks post op, I was eating 1200 calories a day in 6 (or more) little meals.

You’re still healing. A lot of nerve endings were affected during surgery & they need time to heal too.
The more liquid a food the less likely you’ll feel any sense of fullness as liquids pass through your digestive system more quickly. So it’s not until you get to soft foods or solid foods that you start to feel full.
I ate about 1/4 -1/3 cup depending upon what I was eating. I was given serving sizes not calories or weights to follow. Took 3 days to eat a serve of rolled oats & the same to eat 2 scrambled eggs. Of course I could have a lot more if it was a liquid or soup but always ate/drank over a long time. In saying that, we’re all different & there are lots of different plans out there. As long as you’re not experiencing any discomfort & following your plan, you’ll be ok.
Congrats on your surgery.

fluids go right through you. I'm sure you're fine.

Is anyone finding that post op they are having trouble differentiating between hunger and being full?

I am on my 2nd week post opp, I feel like I broke my stomach or maybe she didn’t take out enough stomach??
My problem is I feel like I am drinking more than 2oz!!! Did I stretch my stomach already??? Help me please as I am feeling discouraged
