Persistent vomiting at 12w2d

Cadence
I have hyperemesis. I've been vomiting steadily since 5 weeks. I'm 12+2 now. I take diclectin, gravol, and zofran (all prescribed by the specialist). The zofran has helped me be able to eat sometimes. But I feel so sick everyday and I don't know what else can be done other than to suck it up. On bad days I vomit several dozen times, and on good days maybe only 10 times but I gag all day long. Has anyone else experienced this? How long did it last? Any other treatment recommendations? I have been to the ER a few times to monitor for dehydration.
