Hyperemesis Gravidarum

As
Hi ladies,
This is my 2nd pregnancy. With my first I had hyperemesis horribly. I was always in the hospital, lost 25 pounds, and racked up $80,000 in medical bills. Zofran was the only thing that helped. 
This time I have the same thing. I was in the hospital Monday for 6 hours hooked up to IVs again. I called my doctor because the oral zofran isn't helping anymore. I can't go into the hospital 4 times a week again and not be able to eat. Has anyone who's had HG requested a picc line or a zofran pump? or know If it's possible to request one? I'm in Chicago, IL. 
Any help would be appreciated
