OMG I hate that ur going thru this, but this is the exact thing my doc told me to do. I have been so weak and the hunger pains are pains i have never experienced in my life. He told me 2oz every 2 hrs no protein or vitamins until I saw him next week. This in my opinion is crazy and does not make sense. The human body needs calories, vitamins and protein to function let alone heal from surgery. I cried for 2 days straight and after asking many ppl on here finally said screw him. My boyfriend went and got me Kellogs K2O and that has helped take the edge off of the pain. It also has a tiny amount of b6 and b12. I don't know if it was in my mind, but yesterday I had more energy. Don't get me wrong I'm still starving, but not at the point of tears. Everyone tells me that I will get thru this hell and its worth in the end, but I am counting the days down. I knew it was going to be rough, but never had any idea it would be this bad. Good luck!
