they may be willing to prescribe you zofran or phenergen, but you have to tell them that the reglen doesn't work for you. some OBs won't prescribe the other two i mentioned, but some will, so you just have to give it a shot. Have you tried any home remedies? (i.e. eating small, light, more frequent meals...ginger ale or ginger root tea, sucking on ice cubes, eating crackers/toast?) they sometimes help more than medicine....but sometimes not.
