Hello, I Have Been Vomiting Most Foods That I Eat

Hello, I have been vomiting most foods that I eat everyday after having my gallbladder removed 2 weeks ago. I have lost 20 pounds. I am able to keep most liquids down but nothing solid. I have tried different foods, mostly bland and small portions. I am not in any pain or have any fever. Incisions have healed from laparascopy. Returned to ER and Surgeon's office. They ran x-rays, no blockage, pancreatitis, negative, h. pylori, negative, blood work, normal. The surgeon has had me on Phenergan and zofran, does not work. Also tried me on antiviral medicine, does not work. Surgeon doesn't think its bile reflux, gastritis or sphincter of oddi. Very weak from lack of nutrients. Any suggestions?
