You are NOT alone...I woke up from surgery STARVING!!! I was so hungry that the next day I was sick, sick, sick and ended up having to be brought back in and given an IV with "lunch/dinner", electrolytes, and vitamins! It was such a good thing for me to go back!!! I am hungry, everyone is different. They actually put me on proteins the following day!
The Dr. told me, "eat, eat, eat (soups/protein drinks) and drink. If you are hungry and need 9 Slimfast, then drink 9! If you need to keep eating broth, then keep eating it!" So, there is your answer! Just don't gulp it down, sip it and you should be fine!!! Good luck!
Oh, by the way, I just was banded a week and two days ago!!!
