Hyperemisis Struggle

Looking for tips and such to get a handle on this. I don’t know if age is a factor I have a 10 & 6 year old and zofran did the trick for me with them. This go I am barely surviving I feel like. One day I can eat toast the next day I’m holding the toilet. That’s how it has been, I do really good with food one day and the next it’s bad. Mostly bad days tbh. I try to eat and eat small meals as recommended but it just comes up at the end of the day. I’m so weak and tired anymore with it that I feel like I’m a burden to my hubs and I am failing my other babies. I just need some advice/suggestions on how you all may have dealt! TIA 😘
