anyone else diagnosed with hyperemesis gravidium/ severe morning sickness?

Danielle • 4th pregnancy. 1 miscarriage. 5 year old girl and 2 year old boy. 💙💖 Due January 2018!
I'm in ER for round 2 of iv fluids after almost passing out. My heart rate jumps when I go from sitting to standing and I'm extremely dehydrated. I've lost some weight too. I can't stomach anything and I've tried lots of otc remedies and 2 naseua meds. What helps you ladies?!?!
