Bonjesta alternatives?

Kera

So, I suffer with extreme nausea & vomiting. I am 7 weeks and 4 days today. My doctor prescribed me Bonjesta which isn’t covered by my insurance and the price came up to $748. That’s ridiculous and I’m not paying it. Does anyone know of any alternatives? I am absolutely miserable & on the brink of depression because I’m always so sick.
