My mother is in the final stages of 4th stage lung cancer . After three different rounds of chemo , her last chemo treatment ended in June, 2012. We ve been trying to make her as comfortable as possible. The problem is that she vomits daily - whether she has salad or chicken noodle soup or a more rich meal like mac & cheese, turkey and dressing. It seems to come up whether it s light, medium or heavy. Do you have any suggestions
