Hyperemia- HALP

Anyone else out there struggling with hyperemia? I’m tired of living on the bed/couch but I feel awful all the time. Without zofran I vomit several times a day, sometimes several times an hour! I’m constantly dehydrated and bloated and constipated, dealing with heartburn making me gag and then the nausea. The more I move the sicker I get. Food is awful and the only things that stay down are processed junk. Water is hard to keep down most days because stomach is so sour even if I haven’t eaten all day! I need some hope if anyone has dealt with this and have suggestions. If someone has dealt with hyperemia in a previous pregnancy, when did it taper off? Feels like I can’t do this
