Really struggling - Hyperemesis Gravidarum

I’m 6 weeks and really struggling with Hyperemesis Gravidarum. I can’t keep any food or liquids down. I throw up 15 plus times a day and feel absolutely horrible. Anyone have any advice? Anyone in the Denver area know of a specialist? I’ve tried every ginger item, saltines, small sips, B6, tums, been prescribed zophran, phenirgan. I was admitted into labor and delivery at the hospital after going to urgent care and then being sent to ER. They prescribed me the above but nothing is helping. Does anyone have any advice?
