Help hyperemesis gravidarum

I have really bad nausea sometimes vomiting. Have Ben laid out on the couch unable to function and already been to the hospital twice for dehydration and to get fluids. The only medicine I haven’t tried is Diclegis which my dr ordered but it’s out of stock til sube today or tomorrow. I feel nauseous all the time and it’s awful. Yesterday at the ER they told me it was hyperemesis gravidarum. If you’ve had this before please tell me what worked for you and what you did.

Thank you
