I just had my surgery tuesday and starting today I made 8 oz. protein shake and I couldn't even get one down. - probably had 4 oz. I'm suppose to have 5 shakes a day. I'm like there is no way right now. Maybe later on it will get easier? All I'm doing all day is sipping on vitamin water and I did have a can of low sodium beef broth. The shakes I drink are optifast.... I would make them with less water but.I think the thickness of it is what bothers me. I'm on liquids for two/three weeks depending on my progress. Ill find out more on jan 9th. I hope it gets easier because right now I'm starting to wonder. Lol
