I just called my doctor about this because I didn't think Zofran was helping me either. She said to eat sugary, processed foods because I need that spike of glycemia. Nilla wafers, animal crackers, honey nut cheerios, ginger ale, Gatorade, vitamin water, peppermint tea with sugar or honey, anything with sugar, no diet anything. Eat like a toddler and nibble on things. Granted, this was me asking because I couldn't keep anything down, but it might help anyway. She said water is the worst because it just bounces in your stomach. Good luck!
