I had my surgery on May 4. After 4 days the nausea subsided make sure you take the zofran and if the offer additional nausea meds while your stay in the hospital get them. They also gave a a patch that goes behind your ear that is good for 3 days for nausea.As for pain they did give me norcos but I don't like taking them. Fyi they do contribute to nausea so i just took extra strength tylenol for about 3 days after surgery. I do on occasion have incision pain but an ice pack works fine. As for preop diet they didn't put me on a full liquid diet. It was more of a high Protein low carb diet and it worked I did lose 10lbs in 1 week. If i can ill post diet as attachment. Well good luck to everyone and hope all have a speedy recovery.
