Today is my second day of pre-op high-protein liquid diet. First day went okay but today by second protein drink (20 g) began to feel very nauseous. Had third protein drink this evening and nausea came back even worse and not hungry at all. Has anyone else felt nauseous doing the pre-op protein liquid diet?

@@Catcutie I never felt sick from my protein drinks during pre-op but you may need to alternate Between drinks of protein and drinks of water to thin it out a little or try a different shake. Good luck!

Thanks Elode.

I split my Protein serving in half, with more Water and didn't take Multivitamin. It seems to have helped - still queasy but nothing like yesterday.

I was told the first two days are the worst. Does your protein taste bad to you? I enjoy my shakes.

The Miracle whey I got from Mercola tastes awful to me, but the Premier Protein drink is decent, though almost too sweet.

Talked to Dr. office about the nausea today and they suggested taking an acid blocker to see if that helps, and if not they will prescribe an anti-nausea med.
