Nausea

Have you ever been nauseated and could not eat? The sight and smell of food made you physically ill? My husband has felt that way now for about 3 weeks. The hospital could not find anything that would help or a cause for the nausea. However, another Dr. suggested a patch that can be put on your shoulder that will take care of that. I am on my way now to the pharmacy to pick that up and I sure hope it works.
