Hyperemesis gravidarum

have any of you ladies been diagnosed with Hyperemesis gravidarum? I have a co-worker that has been diagnosed with it and I want to make her a basket of snacks and drinks she said she can barely keep crackers down on her good days. I know that everyone is different I just want some ideas on what to get her to try and help her. she helped me so much through my last pregnancy so now I want to help her. Tia!
