What are good things that help with or cure hyperemesis?

My best friend in Utah is pregnnant for the second time and she “feels like death”. I bought her a book called Preganacy Sucks. I think she might have hyperemesis, which is the constant vomiting and naseua. Basically, the worst kind of morning sickness.
She can’t keep anything down, including fluids. I want to help her as much as I can, but I’m a few states west of her. Her family is calling her lazy and her husband’s family is just as bad. Save for one of his sisters and his friends.
What can I tell her or send to her that might help? I’m sending out a care package with the book tomorrow afternoon and I’d like to get things that I know will work, besides drugs. She’s really not into taking them. Suggestions?
