I’m three weeks out from VSG and I can’t even approach my hydration or protein goals.

I had VSG on June 10th and I’m currently on soft foods. I’m healing up great and I’m crushing my weight loss goals. My major problem is I can’t bring my self to hit my protein or hydration goal. Hydration I’m doing better on I’m at least in the ball park most days I usually average about 40-50oz. Protein on the other hand I think in I got maybe 15g yesterday and that was from food. I for some reason can bring myself to do protein shakes. I even have ones that I like and I can’t do it.(Yes I’ve tried the juice ones and unflavoured I hate the taste of both) It doesn’t help that I have no hunger I eat when I feel like it not because I’m hungry and I’m not thirsty either I took me all day today to get through 36oz of water. Idk what to do

Should I just force it? Should I contact my doctor or nutritionist?
