Not "really" diagnosed with it ( I refused endoscopies) but I was prescribed domperidone to help with the condition and with my migraines. I do get bloated and nauseous pretty much every time I eat. There's not much to do about it except eat smaller meals more often and drink teas that help with digestion. When I feel very poorly I take the domperidone. I second the idea of a gastric emptying test, if you can get through it. I couldn't do it (was prescribed the test when I was a kid) because it made me too nauseous, but it sure would help confirm the diagnosis.
