Severe sickness

So I have been sick from sun up to sun down, throwing up, can't hardly eat or drink. I am now serve my dehydrated and heading to the ER for an iv. I have been taking Zofran and Reglan daily to try to help the nausea and I still throw up. Has anyone else been told they have severe morning sickness? Where literally nothing works for you? And any tips to try to keep me hydrated besides pedialyte, gatorade, and drinking water. They all make me sick! 😩
