Is the nausea event caused or is more constant? Smaller feedings may help, sitting up during feedings, and not lying down for two hours. I only used water to clear the tube, before, after feeding, if I used too much water it caused nausea, vomiting. I used the water for hydration another time, after feeling digested. When getting up, do it slowly, rather than quickly, otherwise than can cause nausea vomiting too. Good luck.
