For the last few days I've been really really nauseous and it's been hard to eat anything because I think it will make it even worse.. Any suggestions that might help?

Immediately after gastric bypass surgery, the most important requirements are Protein, fluids and Vitamins. food is secondary because your body is converting stored fats into the energy that drives your body. Thus you lose weight. So are you able to meet the protein, Fluid and Vitamin requirements? This should be your focus.

Did you have RNY surgery? How many days post-op are you? What are you trying to eat?

I have the same issue. See if the Dr will prescribe either Zofran or Phenegran cream.

drinking warm tea helps sometimes
