Nausea after chemo has ended

I am nearly 2 months out of chemo therapy for Breast Cancer,  but still feel nauseous all the time.  My mouth waters like it would if I was going to vomit, but I don't.  The thought of food makes me sick to my stomach and when I do eat, my throat feels like I'm eating glass.  Has anyone experienced these syptoms.  I am getting little satisfaction from neither my Primary Physician or my Oncologist.  They recommend a gastroentologist  but I can't believe I am the only person to experience this.  I have been unable to return to work due to this continued illness.  Anyone have advice for me.  None of the anti-nausea medication has worked for me either.
