Fruit pectin and flat ginger ale?

Nothing helps me with my nausea, I've thrown up 10 times today, and everyday for the past 3 weeks. I talked to my doctor and was really surprised that she didn't seem concerned that I've lost 28 pounds since finding out I was pregnant! That seems very scary to me. I've tried all pregnancy safe nausea meds that I know of, and a pharmacist at Walmart suggest this to me. 1/2 fruit pectin with 1/2 flat Ginger ale. Has anyone heard of this? I can't find anything on it! And does anyone have any other ideas? Thanks!
