After having lost 30 pounds and suffering from severe stomach cramping and unable to eat much, I had a gastric emptying procedure and diagnosed with gastroparesis. Have had for about 6 months now. My gastroenterologist prescribed a medication, (not FDA approved, so I get from Canada) 50mg domperidone. I take before I eat and 1 before bedtime. The excruciating pain is gone, but still have the discomfort of feeling full all the time, but no more pain. Weight stabilized and haven't lost anymore but haven't gained any back. I'm told I will always have this. No cause (possible virus), no cure, and now I do sleep. Hope this is helpful to someone
