LOL....sorry but take a chill pill. It takes a while to lose the fluid from the hospital. It will happen. Did somebody tell you that you would lose 150 pounds the first week?
Just focus on staying hydrated. Getting in at least 64 oz of fluids a day is job one.
As far as eating, remember the 30, 60, 90 target for protein. By day 30 post op you want to be getting in 30 grams of protein, by day 60 you want to be at 60 grams, day 90...you get it. These are just goals and if you can do more, that is icing on the cake but if you can't hit the targets it isn't the end of the world. The stomach is messed up at this early stage and can only handle so much so do not let food get in the way of hydration early on.
I just saw you are getting in 100 grams of protein already. Wow! That is great as long as you are getting your liquids . Is that all from protein drinks or is some food?
The weight is going to come off so don't fret. Always remember this is a marathon not a sprint.
