Are you just doing shakes? I was on Clear liquids so did lots of Jello and SF Popsicles to help me through.
Can you call the nutritionist for advice? You have to ask for help and be honest.
Good luck
I had my surgery 10 days ago. Took a week to start losing wt. gain from surgery. Now starting to go down a bit. Stay strong, drink, and follow your MD orders.
