I had hyperemesis is gravidium too I was in the hospital for a week I'm on zofran and it helps I'm still a little nauseous but it's a lot better than it was.
I try to eat nothing ever stays down i am keeping some liquids down
You hafta get food down. I was hospitalized twice for it and they had to pump 12 bags of potassium in thru my I.v. it is very serious.
No meds worked for me except vikadin (which is safer than the nausea meds anyway but u can't take it all the time or u will get addicted. Weed works too and is safer than any meds.
