My neurologist prescribes 250 mg of Erythromycin to be taken 3x a day (total 750mg daily) to help control symptoms, and it works. Does not fix the problem, but without the Erythromycin I have the severe nausea, vomiting, bloating, and cramping but when I take the Erythromycin and eat small, carefully selected meals, I find that between the two it's much easier to control and sometimes I have days where I have no nausea at all. My delayed emptying problems are due to neurologic disease, so I don't know if this will help you or not, but I hope it does. I second Jane's comment---you are not alone. Sending well wishes, always.
