Hey, sweetheart, calm down! I know it's hard and you are doubting a lot of things but the hunger..the hunger is only in your head. It will pass. I'm a new sleevee as well, I'm just over 6 weeks out of my surgery and until 1-2 weeks ago I has the same questions you had. Why am I hungry? Did the doctor not cut 85% of my stomach and so on!
You'll see, this psychological hunger will pass soon, wait and see and don't despair!
As for feeling slightly full..that's normal when you're downing liquids or creamy liquids or shakes etc.. Our new sleeved tummy will take in a lot of liquids , don't worry, its normal! Of course your tummy is not stretched out! Don't be silly!
And for the sleeve itself ...is not an exact science , its impossible for the doctor to cut exactly 85% of the stomach but its pretty much around that size!
I really hope you'll feel better soon and stop worrying! I did worry too and at 3 weeks I already hit the first plateau when I started solids but the weight started melting again after a week. I'm down 40 pounds in 6 weeks and my starting weight was 280. So cheer up, everything will be perfect! I wish you all the best xx
