I was told the same thing by my doctor, to drink more fluids. For me it was/ is a real task drinking the required amount.. I felt like i was starving too! But i do think it was mostly head hunger,and missing the texture of foods. I was especially feeling it when i had to see family members eat things i love , like pizza,etc. in front of me..I'm on my 3rd week puree diet,i feel alot better now , and happy to eat "babyfood" lol..Hang in there! also if you dnt have it already the UnJury protein soup helped out alot. I added curry spice to it
