From what I have read the severity of the symptoms is not directly related to the emptying time. This is the case for me…my emptying time is mildly delayed but my nausea is constant. I have tried many medications none of which have worked so far but I am not giving up. Currently I am taking Domperidone (although prescribed it is not FDA approved and it has to be ordered from another country or made at a compounding pharmacy). Botox injections are sometimes an option. There is a yahoo group for people with gastroparesis that has alot of good info and also this website G-PACT.org.
